Aitah for not wanting to go out with my cousin or her fiance who makes more than me because of her scamming nonsense shenanigans?

So I was born on Christmas We were going to celebrate the day after Christmas and my birthday at a restaurant. They do this thing where they demand to go to a really expensive restaurant then don't bring any money. My older brother always pays. I told him he shouldn't have to do that

They can afford to pay. If no one pays they go from table to table with a bs story begging for money. They do this everywhere. I refuse to go anywhere with them because of it. people say things to me like you should help your family. I said I don't know why she is doing that. She is richer than me?

I want to go outback because I have a gift certificate that was a bonus from work and it's my birthday. It will cover everything. I offered for them to come to the house and have maple bourbon pork chops apple cobbler a nice salad and instant mashed potatoes. Eww 🤮 they said. I also have starbucks cards and a gift card to a pizza and wing place cracker barrel. Not good enough for them.

They then call yesterday and are like hey we have 250 dollars to take you and your fiancee out. I am like oh cool. Are you for real because if you really can't it's ok. I get up the street and they are like psych! We don't have enough gas to get home you want to go panhandle with us for gas. I got out and said no you all are being stupid and walked up The street back home. they say I am being harsh and negative. They keep texting me sorry and asking to go out. I am going out with mother in law friends and fiance for new years. My older brother. To outback. they aren't invited.

Seriously my step niece is 14 and my friends children came for my birthday they are 4 and 7 they acted more mature than my cousin. She's going to get arrested if she keeps doing that.
