AITA for changing all the locks on my house because my girlfriend keeps locking me out of the bedroom at night

The user, a 29-year-old man (OP), purchased a house where he lives with his 36-year-old girlfriend. Early disagreements involved allocating space within the home, resulting in OP taking a smaller office while his girlfriend received the second-largest room for her office and occupied the second living room for her use. The main conflict began after an argument regarding financial responsibility for house issues like pest control and modifications, where OP agreed to cover all costs.

Following a subsequent argument where OP admits to yelling, his girlfriend began retaliating by locking the bedroom door at night, forcing OP to sleep elsewhere. This pattern repeated after a brief reconciliation following a vacation. After returning from a two-week work trip to find the door still locked, OP changed all the locks on the house, leading his girlfriend to record him. OP is now questioning whether his frustration and subsequent action of changing the locks make him the person at fault.

AITA for changing all the locks on my house because my girlfriend keeps locking me out of the bedroom at night

My girlfriend (36F) and I (29M) moved into a house that I bought last year. We argued at first about what each room should be. 3 bedrooms, 1 1/2 baths, 2 living rooms, a garage and a back patio.

I wanted an office and she wanted an office. At first I didn’t want to but I gave her the 2nd largest room for her office and the largest became our bedroom. I took a significantly smaller room for my office.

She occupied the 2nd living room for herself.

We slept together in the bedroom, as would any other couple for the first few months. We had arguments here and there but nothing major. After about 3 months, we had a big fight about decisions involving the house.

Pest control, upgrades, modifications, etc. She said since it’s my house, she will not be bearing any of the financial burden that would come of disposing of the pests and any issues that would come up with the modifications.

I wasn’t happy at first but in the end understood her point of view. I took on the financial responsibility. Shortly after this, I got mad and yelled at her during an argument regarding the pest control and the modifications she wants.

It was after that point she started locking the bedroom door at night, forcing me to sleep elsewhere. I tried taking the bedroom earlier than her one night but she just sat there, keeping me from sleeping until I left the room.

It took about 1 month for her to get over it and we started sleeping together again. This was shortlived. We went on Christmas vacation together, all expenses paid for by me. First class seats and fancy hotel.

Vacation was great. Once we got back, we ran some errands together and upon returning, she refused to bring anything inside. She was distant and shut the door on my while I was bringing things inside.

I confronted her about it to which she said “I needed to get into the closet, I didn’t care about your needs” to which I yelled at her again. She went right back to locking the bedroom door on me.

I went away for work for 2 weeks and once I returned, she still locks the door. I was fed up with it and changed all the locks in the house. While I was changing the locks, she started video taping me and asking what I was doing.

I know my yelling is a direct result of the actions she’s taking but Am I The Asshole for getting fed up with getting locked out of my own house?

PS: I haven’t look her out of anywhere except my office. She still has access to the rest of the house.

Here’s how people reacted:

NTA I agree with others, its time to evict her and find a stable woman to date, but I’m pretty sure your not going to do that. So, she can use the 2nd living room as her office, she doesn’t get to take up more of your house that you do. She also needs to start paying you rent and I really hope she is already paying 50% of the utilities, of which she also needs to be paying 50% of the pest control. And what are you even talking about “the modifications she wants”, THIS IS YOUR FREAKING HOUSE DUDE start acting like it, reach down and grab your testicles and put your damn foot down. She doesn’t get to “make modifications” to your home that you then pay for. She doesn’t get to live in your house for free, she doesn’t get to use more of your home than you do, she’s your gf not your wife, man up.
Otherwise_Degree_729

YTA. Evict this person. She is making your life a living hell and will only worsen.

She has the primary bedroom, the secondary and one shared living space occupied and doesn’t want to pay for anything.

She will sue you once you try to break up with her. That’s why she is recording you when you’re pissed off.

Get cameras, get a friend to move in temporarily so you have a witness and serve her an eviction notice.

VegetableBusiness897

Duuuuude…..she has the largest room(bedroom), the second largest room (her office) AND the second living room. You have two rooms *in your own house that you pay for*!!!!

Move into the bedroom, use both the living rooms, move her to the smaller office. Tell her it’s either that or she can pay 2/3 the mortgage for her rent.

Temporary_Bug_1171

NTA but you will be if you stay with her. She sounds toxic AF. She needs to go find her own place to live and then she can lock all the damn doors she wants to. You can’t trust her. The whole videotaping bs sounds like she’s trying to manipulate you and set you up.
Accomplished-Fun-72

You are only the asshole to yourself for putting up with that succubus. That “relationship” is just her taking your shit and making you feel bad for owning a house. It’s not hers. Tell her you need space and make her leave for a week.
Caspian4136

Why the hell are you still with this shrew? What could you possibly get out of this relationship? She’s locking you out of your own bedroom, in the house you own!!

Dude, it’s time to end this and get her out of your house.

Upbeat_Vanilla_7285

Dude. Move on! She’s immature and doesn’t know how to communicate. Why does she think she can kick you out of your own bedroom in the house that you pay for? I’d call the police next time and have her escorted out 
Total_Bee_8742

Are you that desperate that you put up with this woman and her nasty garbage. It’s your house. Open the door. Toss her out. Toss her possessions out. Close the door. Then lock it. There fixed your problem.
redelectro7

Why are you with this person?

If she doesn’t financially contribute to the house why are you giving her the larger room for her office and getting kicked out of your room?

Kick her out, end the relationship.

Clean_Factor9673

NTA except to yourself. She should be paying rent; don’t call it a portion of the mortgage because that implies equity.

Evict her. She has no right to lock you out of any part of your house.

corgihuntress

Why are you still with her? Seriously. You two sound like unhappy roommates and not partners. You are the landlord/owner. Charge her rent or make her sign a lease. Better yet, evict her. NTA
VoidIgris

You’re a fucking dumbass. Call the cops and evict her. You’re the doormat who’s letting the dumb botch take over your house. Make sure the cops are there before you evict her. 🤦‍♂️
EveryCoach7620

Both are AH. It sounds like a toxic mess at your house. She needs to move out and you need to move on. PS don’t ever yell at someone you love or care about.
tigerz0973

Why are you still in this relationship?

It seems like she really hates you and emphasises it constantly by locking you out of your bedroom for any reason!

Fragrant_Spray

I don’t think changing the locks is a solution. Your gf needs to exit the premises. It sounds like you have an entitled house guest, not a partner.
lchornet

NTA. She is using you and appears to only want material things out of the relationship. Start the eviction process and break up with her.
Icy_Material_4387

NTA. I had to scroll back to double check the ages here, this relationship sounds exhausting. You should definitely send her packing.
Impalmator2

You’re her doormat. You need to break up ASAP, but you should consult with a lawyer first cause it will get nasty. Get ready for war.
Useful_Context_2602

What are you getting out of this “relationship”? YTA to yourself staying with her based on what you’ve posted here
Aloreiusdanen

Dude, why are you a woman who is 36 and still acts like a child by locking you out. Break up and find an adult.
Artistic-Tough-7764

WHY is she still in your house/your life???

Change the locks to the FRONT door, back door, garage door.

Deb_elf

NTA. But you’re not compatible. Time to send her away, heal and date someone who’s not as entitled or mean
DontBeAsi9

You are the frog. The water is boiling. Please jump out before you are cooked completely.

NTA.

Time-Improvement6653

Get the eviction process started – it’ll likely be a long one, but worthwhile and necessary.
chaingun_samurai

She wants to play that game on a house that she doesn’t even own? Yeah. Bye.
rahrahsan

NTA. Evict her and move on otherwise this is going to keep escalating. 
FaraSha_Au

Yeah, NTA. Chick has a screw loose. Eviction is your best recourse.
Affectionate-War7655

This is abuse.

Forget changing the locks, change your girlfriend.

RJack151

NTA. Dump her and send her packing. This is YOUR house, not hers.
AlternativeLie9486

The door you need to change the locks on is the front door.
DigitalBoy05

Cut your losses, serve an eviction. Document everything.
Muted-Inspector-7715

Dude wtf is wrong with you?! Get her ass out of there.
garybwatts

She’s no longer your girlfriend, just a roommate.
InstructionEarly1969

NTA, there are so many red flags here..
MikeReddit74

NTA. She needs to go, and quickly!
drocka2021

break up with her and evict her

Conclusion

The core conflict revolves around the OP’s response to his girlfriend’s chosen method of conflict resolution: punitive isolation by locking him out of the shared bedroom. While OP acknowledges his own unacceptable behavior of yelling during arguments, his girlfriend’s consistent use of bedroom exclusion acts as a controlling measure that escalates tension rather than resolves underlying issues. The OP felt pushed to an extreme measure after repeated attempts to communicate failed.

The situation presents a clear impasse between boundary setting and punitive control. Is the girlfriend justified in using the bedroom lock as a defense mechanism following conflict escalation, or does OP’s ultimate action of changing the locks represent a necessary, albeit extreme, response to reclaim his space and establish a different behavioral contract? Where should the line be drawn regarding acceptable retaliatory actions in a shared living situation?
