 My father-in-law and I have a fairly good relationship and both he and his wife have helped us out a lot - help with the house (fixing issues), help with daycare (monetary) and even help with putting down a loan for the car. They are both retired, are fairly well-off and have over $500k in their bank accounts. We have a long-standing tradition of going to brunch on Sunday and because my wife and I struggle with finances with having two children, a car payment, a house payment, etc., we cannot afford to pay for these brunches. Our in-laws know this as they were previously in the same profession, but it doesn't stop my father-in-law from making jokes about picking up the tab, giving me a car loan ($2000) and paying for daycare. I've told my wife this that he only gives me a hard time and doesn't say anything to his other son-in-law and that if he continues, I will simply refuse to go on these brunches. She has talked to him about how the jokes make me feel and he acknowledges that he gives me a hard time and that he'll try in the future to stop. We have since stopped asking for help with daycare and I will have paid off my car 2.5 years early so that I can pay him off for the car loan.

Well, lo and behold, while all of us were shopping in a bookstore, he made an unhappy gesture to his wife, who was purchasing several books and wanted to purchase comics for our children, that since they paid so much for us that she needs to stop buying stuff for the kids. I got fed up, paid for everything (her books were $30 compared to the $5 that she wanted to pay for the comics) and was livid that he continued to bring up the issue of money. I have since stopped going to any family function that requires SOMEONE has to pay. I told my wife under no circumstances should my decision affect theirs in spending time with her parents and allowing them to see their grandkids because it's not fair to them.

AITA for refusing to go these family functions because he continues to make money an issue or AITA that needs to acknowledge that he's just making playful jokes that I am taking too personally?
