AITA for not taking my nieces to the park after the way my SIL treated me?
I 28F have an older brother who's married and have two kids. My brother and I have always been close and I adore their kids. I don't have children of my own yet (my husband and I have been married for 4 years and we've been trying to conceive for 2 years now). they often ask me to babysit. I also take them to the park sometimes or just hang out with them to give my brother and his wife a break.
Everything was great until last weekend. I had planned to take my nieces to the park for a couple of hours. My SIL called me in the morning and asked if I could pick up some groceries for them on my way over. I agreed no problem. When I got to their house with the groceries my SIL was visibly annoyed. She started going off about how I got the wrong brand of butter and that the fruit I bought wasn’t fresh. She even complained that I was few minutes late which was because of the extra stop I made for the groceries.
I tried to brush it off but she just kept going making comments about how "don’t understand the stress of raising kids" I finally snapped and told her she should be grateful I’m even helping out. She said she doesn't need my help if I'm going to have an attitude. I told her to deal with her own groceries and left without taking the kids to the park.
Now my brother is upset with me for "abandoning" (edit: sorry I meant to say "punishing" not abandoning) the kids and not keeping my promise to them. He says I should have just let my SIL’s comments slide for the sake of the kids. I feel bad about disappointing my nieces but I also feel like I shouldn’t have to put up with that kind of treatment.
