The MIL also suggested renting a luxury car for $1300, which the OP declined, citing affordability issues as they already had separate birthday plans. Now, just days before the reservation, the MIL unexpectedly texted the OP asking if they would need help paying for everyone’s dinner, leaving the OP feeling uncomfortable and unsure how to respond to this sudden financial query.

My mother in law texted me a few weeks ago to invite some of my husbands friends to a surprise birthday dinner. She gave me a list of people to invite and asked to call and make the reservation, so I did, happily.
She first asked me if I wanted to go slits on renting a luxury car for the day which would be $1300!?, I told her I couldn’t afford that, especially as we have our own birthday plans made (we’re going away for the weekend).
I’m not rich by any means lol. It’s a few days before our reservation, and she randomly texted me asking if I’m going to need help paying for dinner for everyone??? Is this normal?
I can’t afford this? what the hell do I say to that? I feel so uncomfortable. AITO if I tell her everyone can pay for themselves?
Conclusion
The central conflict revolves around the OP’s discomfort stemming from the mother-in-law’s escalating financial expectations regarding an event she initiated. The OP feels pressured by the sudden request for financial contribution after already handling the organizational tasks.
The dilemma is how to address the MIL’s implicit expectation of subsidy: should the OP firmly state that guests should cover their own costs, or is there a more diplomatic way to manage the finances of this surprise dinner?
Here’s how people reacted:
Time to talk to your husband. This is MIL’s surprise and she is taking advantage of you. And she is relying on you saying “Yes” to everything because she knows you are a people pleaser.
Stop dealing with her directly. Let hubs deal with MIL and her expectations of you planning and paying for her surprise dinner. She may complain that you are spoiling the surprise, but imagine how your husband is going to feel about you paying for everything when you didn’t plan and budget for this event. Does your husband even want to have dinner with these people? Maybe they are just her friends?
The only rational response is –
I have been happy to help you with the planning for your party but I cannot afford to pay for it for you.
Any response after that can be answered with:
Had you told me upfront that you were planning a party that you expected me to pay for I would have told you that we cannot afford this.
However, I am happy to contact everyone and let them know that although I was happy to help you with organizing, unfortunately, the party is canceled because you cannot afford it.
Beyond that, the time to **speak up** would have been when she asked if you were “okay paying”. For not doing at least that, YTA. (I’d have exploded at her.)
I’d phrase it to say that you were happy to make the reservations but not necessarily foot the entire bill. It should be understood by all invited that they are to cover their meals, drinks, etc. and you are happy to pay for you and your husband. If her intention was to have you pay from the get go, it should have been discussed from the start.
You already spent your money for you and husbands weekend get away.
Make sure you and husband leave your credit cards at home.
You need to make it clear that you have no intention of paying for anyone other than perhaps the birthday boy. Make sure the friends know that too.
Does your partner actually like surprises? If not they it might be best to bring him in on the plans.
I’m unclear why you’re confused as to what to do. Are you afraid of your MIL?
You must advocate for yourself. No matter the awkwardness
You got this
Tell her you and your husband won’t be attending.
NTA
Tell her point blank you aren’t paying. This is her idea and she needs to figure it out.
Just no
You need add no further words, none
Spine. Use it
