Just ranting - my SIL is pregnant and expects special treatment

My SIL and brother are expecting a child. Due to personal reasons, I will not be going to their baby shower, although I got a gift, nor will be involved in their lives or their kid’s life. Maybe when the kid is older, but while the kid is still of the age where I have to interact with their parents, then no. Long story short my brother was horrible to me all my life and he did something else which just finally broke my camel’s back and I’m going to go low contact with them. They’re both not great people. My parents don’t like that I’m doing this but I told them he was never good to me and it’s my choice, get over it. I’m so sick of the ‘but he’s your brother/family’ excuse he’s a POS is what he is.

Anyway, my SIL was a huge bridezilla 2 years ago when they married. I’m talking she made the entire year about her and demanded all this attention and parties etc. I knew that meant she’d behave similarly when she got pregnant. Well, fast forward to now and I was right. I spoke to my mom yesterday and my mom let me know that apparently my SIL is disappointed/annoyed/upset that I haven’t been reaching out to her to ask how she’s been doing since she got pregnant and if she needed anything. Mind you, I found out in late January. It’s March.

We never spoke much before she got pregnant, but now she wants me to be checking in on her occasionally and doing stuff for her? Ummmmmm NO. That’s what your husband is for. Sorry I’m not going to make the entire year about you just because you’re pregnant. This is literally what you wanted so?? Also I’m not going to suddenly talk to you or dote on your just because of that. Grow the hell up.

Sorry just wanted to rant
