AITA for telling my girlfriend that we are not living together if she wants to split joint expenses proportional to income?

A 28-year-old man (OP) has been in a relationship for two years with his girlfriend, who is currently in graduate school and living on a small stipend and student loans. The OP lives rent-free in a house owned by his grandparents. Due to rising rent costs in her current location and her significant financial obligations, the girlfriend wants to move in with the OP.

The central issue arose when discussing how shared household expenses would be managed. The OP proposed a strict 50/50 split on joint bills, while the girlfriend insists on a proportional split based on income, which would leave the OP paying the vast majority of the costs. When the OP stated that cohabitation is conditional on the 50/50 arrangement, the girlfriend became upset, claiming he is adding unnecessary stress to her life. The core dilemma facing the OP is whether to agree to the proportional cost-sharing to allow her to move in or to stand firm on the 50/50 split, potentially ending the living arrangement discussions.

AITA for telling my girlfriend that we are not living together if she wants to split joint expenses proportional to income?

I (28M) met my GF two years ago. My GF is in grad school and lives off of the small stipend she receives and student loans. I make fairly good money.

My GF wants to move in with me. I live in a house owned by my grandparents and do not pay rent (at their insistence). My GF’s current rent alone takes up almost her entire stipend each month.

Plus she has a utilities, food, medical insurance, car insurance, car payment, medical bills, credit card debt, etc. The landlord is raising rent and she has not been able to find a cheaper place that feels moderately safe and sizable enough for her and her dog.

So, she wants to move in with me.

I currently have a close friend who also lives here. He pays all the utilities as his rent. My GF wants him to move out if she moves in, which he is fine with doing. I have talked to my GF and stated that if she moves in, we should split the joint bills and expenses 50/50.

She is greatly opposed to doing that and thinks it should be proportional. That would result in me paying virtually all the joint expenses. A 50/50 split would result in a significantly better financial situation for her.

Right now, her living expenses are exponentially higher than her stipend. With this 50/50 split, they would be significantly less than her stipend. I would actually be paying more than I do now with a 50/50 split because I do not pay any utilities right now.

I told her if she insists on a proportional split, then we cannot live together. She is pissed and says I am causing her unnecessary stress. We both can afford the proportional split so that is what we should do.

Here’s how people reacted:

NTA people are focusing on the utilities thing way to much but we can break it down. Right now you have a friend that only pays the utilities for a house even if your electric bill was crazy high that would still average maybe 800-900 a month and I am being generous. In today’s world rent for a studio is at least 1100 probably more plus you still have to pay your own utilities in your own place so friend is getting a hell of a deal. Yes it doesn’t have to pay anything towards the house but that’s cause its his grandparents and he is nta for having loving grandparents who are helping him succeed. On the girlfriend she is likely right now paying and insane rent and utilities all on her own which she has said she cannot afford so he is willing to let her move in and lose his roommate. Right off the bat she is saving at least 1100 monthly. He is now taking on an extra expense he did not have before just for her by paying 50% of the utilities which will be an extra 400 minimum for him. All this time she has been paying her own rent and utilities and she is saving at least 1000 a month I don’t see why it would be so hard for her to also pay around 400 there is not a place in this world that you could live for that cheap. I would be so grateful for an opportunity to only pay that much hea not asking her to pay rent he isn’t making a profit he is offering to save her thousands of dollars a year by living rent free. It’s not his fault she also bought a car with a 700 dollar pmt when she is only living off her school it’s not his fault she takes trips and racks up credit card debt and honestly OP I would consider not moving her in at all. I know you are 2 years in but by moving her in you are giving tenancy rights to someone who doesn’t seem as financially responsible as you. I mean have you asked her what her long term plans are when she is racking up credit card bills every summer. Or why she needs a car so new the pmt is unaffordable for her. These are fundamental issues that would affect your marriage if she is someone who treats credit like it’s unlimited and doesn’t matter and who can’t prioritize her living situation over a fancy car. I am a broke college kid too and guess what my car is a 25 year old Toyota Avalon that I bought for 1500 outright is it super ugly and old sure does it get me from point A to point B has working AC and fills up for about 40 bucks also yes. If you really want to make this work I would say sit down add up her current monthly housing bills and point out just how much she will be saving moving in with you.

I live with my gf and we pay bills proportionally to the income. It’s the fairest way to split, in my opinion, as it allows us both to save as well. With this in mind I’d suggest looking at your expenses and see if it’s possible to split that way with your gf.

50/50 is never fair and should not be a thing for a long term relationship imo. If you split this way then she will suffer more and looks like she is struggling at the moment.

Now there’s the other side of your post. From what you are saying, your gf is not a very financially responsible person. If you really really care about her, I suggest having a conversation on what can she do to ease her spending and depth. Teach her to save and why it’s good to have a saved amount of money in the bank at all times.

Dating someone financially irresponsible can be very daunting, specially in the long term. I would probably not date anyone like this, hence why I think it’s important to talk about finances early on in the relationship.

Do not let her move in until she gets her act together.

1) You already have a good arrangement with a friend that benefits all parties involved. She expects you to end this. There’s no reason your friend would need to move out as she’d be sharing your room.

Her doing this is an attempt to seize control of your home. Make it her home. Do not fall for this. She may not be conscious of what she is doing, but this is a very common form of manipulation.

2) Once she moves in, you will have a very hard time getting her to move out, even if you break up.

3) Her balking at sharing in the expenses shows her intent. She does not see you as an equal partner but someone she can take from.

4) You two are obviously incompatible. The relationship will not work in the long run, and tying yourself to her is dumb.

Etc.

Basically, everything here indicates that you shouldn’t let her move in, even if she changes her mind to split the expenses.

NTA. What I am seeing is that currently you two are on different financial paths. Having a $700 car payment was not a smart move. Charging credit cards to have vacations, and not having the means to repay it off after using it, is not a smart financial move. That stipend may be have to be repaid. I learned people can pull stipends from their student loans. I hope that isn’t what she is doing.

You probably aren’t a great fit for each other at this time or at all.

Letting her stay will only allow her to spend more.

If you are considering this, I would suggest making a contract to ensure she focuses on her education and shows proof she is paying down her debt, she truly sounds like many young students who graduate with a six figure debt and the job market may not meet her debt to income ratio.

This may not be the smartest move for you. Especially if she is making unwise financial decisions.
She has a parent that can help her.

User_whateverr

NTA. It actually sounds like she’s using you for cheap rent than anything else. I think a 50/50 split is fair given she’d still have more money left over than if she stayed I the same position she’s in now. You’re setting boundaries and it’s always something that can be looked into in the future. If she can afford the 50/50 split, she shouldn’t have a problem with it. You’re doing her a favour and it shouldn’t affect you.
kyrosnick

YTA for not ending this relationship awhile ago. Being financially compatible as a must have in any healthy relationship. If you are that far off on how you spend and save, and see money then this will not work long term. Finding a partner that aligns financially is critical to a healthy relationship. Time to move on or you should have moved on years ago depending how long you have been stringing her along.
_ROBIN_SAGE_

NTA at all. This is a relationship deal-breaker level issue. She will not change, and if you married her you would only have all her debt, and no wife, eventually.

Now if gf drops her bs attitude, and takes your very generous offer that she only pay 50% of utilities, ok fine. But don’t let her screw up your business, credit , (or business credit for that matter!) with her reckless spending….

MasWas

I genuinely dont understand how people think a 50/50 split here isn’t a good thing. OP didnt ask his gf to move in with him, SHE asked to move in. Feel like a lot of the comments ignore this key piece of information, they would be right to say it should be proportional if the situation was the opposite and OP was asking the GF to move in with him.
Zappingbaby

Sure, tell her proportional is fine if she pays proportional rent, at market rates.

But as many have said, the big issue here seems to be that she is trying to take advantage of the situation to pay as little as possible. She knows of the arrangement with the current room mate where he’s paying all utilities correct?

ninesevenecho

On the surface you sound like a penny pinching Scrooge. But after hearing your rationale, it doesn’t sound unreasonable. Ultimately, it doesn’t matter if you’re an AH or not – it sounds like you are not compatible when it comes to finances. That’s a big hurdle and predicts doom for your relationship.
Princesscunnnt

You don’t love her you love your money and you’re greedy, you don’t see her as a priority, you don’t see her as a partner you’re growing a future with. Let her go find her man because you aren’t him. Sit in your grandparents’ house by yourself like you need to be.
TicketFree8331

Shits crazy to me that people are saying OP is TAH. She can spend money on vacation and buying a new car but can’t afford rent??? Like help me out here, but it seems like she can’t live within the means of her income and needs OP to help her spending problems.
That-Opportunity-940

No, your girlfriend is a broke person. She can’t afford her own lifestyle and she wants you to fund it for her. That’s wife behavior and she’s only a girlfriend. Until you’re married, she pays her way and you pay your way.
GRUSM

I feel like her financial literacy will cause issues later on so if she’s this difficult about getting free rent then I’m not sure this is a great situation for you to be in while building a business. NTA.
ClimtEastwood

Oh boy. Be careful moving in or moving forward with this one. She is not on the same page as you and it’s not going to change. Ever. Some things are built in to people and this is one of them.
Responsible-Shoe7258

700 a month for a car is absolutely insane for a person in her situation. She sounds like an entitled princess that was never told no. This is an artillery shell incoming, not a bullet to dodge.
Mafer15

Don’t move her in, she obviously wants you to pay for her spending, she will get worse if she knows she doesn’t ‘have’ to pay rent and that you ‘have’ the money to bail her out! Good luck.
ThreadedJam

You are not financially compatible with your girlfriend 🙁

You shouldn’t move in together until you have reconciled your very different approaches to financial matters.

bacc1010

So if she suddenly doesn’t want to work, then you get to shoulder all the expense.

That’s what I read as her intentions.

That would be a no thank you.

webmbsays

Maybe NTA but you’re definitely communicating that you don’t value equity and that she would be a roommate. She values equity. Not sure y’all are a fit.
RainesCarradine

Depends, if you see this relationship long term, then proportional expenses shouldn’t matter. If not, then NTAH
Scouter197

Why is she insistent on the roommate moving out? If he stayed too, that would lower everyone’s expenses.
Delicious-Goose789

You don’t love her, plain and simple. But for some reason,she doesn’t realize this
ZandrawithaZ

Damn seems like you hate her. Tbh I’d break up with someone like you for that
EducationalHeight434

if your financial goals do not align right now, they never will.

walk away.

stopitcorn

Kind of messed up you made your friend pay for your use of utilities
Davismace

Don’t do it. It’s a simple answer really and OP already knows that.
-stefanos-

Maybe your girlfriend is looking to upgrade you to a sugardaddy ?
notoast4u_2

If she’s your future then you need to look at this differently
Zestyclose-Produce42

At first I was like “Gee how much weed are we talking about??”
18karatcake

Damn, a $700 car payment?! What does she drive?
ChrisAroundPlaces

YTA, you don’t deserve to have her as GF.
Lazy_Pressure5215

I don’t see how you’re the asshole here
LongestSprig

This just isn’t gonna work out dude.

Conclusion

The OP finds himself in a difficult position, balancing his desire to support his girlfriend through her financially strenuous graduate studies against his belief that living together should involve an equitable division of shared costs. His girlfriend views the proportional split as fair because of the large income disparity, while the OP sees the 50/50 split as necessary to maintain fairness, especially since he currently pays no housing costs.

The debate centers on the definition of fairness in a shared domestic situation when one partner has significantly greater financial means. Should the financially secure partner absorb the majority of shared costs to alleviate stress on the student, or is a strict equal split the only way to ensure both parties maintain clear financial boundaries and responsibility for joint consumption?
