Little bit of a backstory but not too much as I simply don't think it's relevant. Me and DH have always kept ourselves to ourselves from the beginning. If invited to a family party or event, we would always turn up and show our faces though because while DH simply doesn't care, I like to keep everyone happy. There's been a a lot of things that happened or been said in the past few years that just threw everything back in my face essentially. I have always made an effort with his family(MIL, his brothers and sisters and their kids), sometimes maybe a bit too much. As I said, I like to make and keep people happy. This is never ever given or shown back to me from their side. Great. So BIL's girlfriend gave birth over a month ago and we still to this day have not been invited round to see them and congratulate them even despite me texting her regularly to see if baby is ok, how she's adjusting, etc. (To which I never get a response to btw). Everyone else in the family has seen them multiple times since and they've been out and about. It was DD's birthday last month and BIL's girlfriend said her son could not attend her birthday party for her cousins (which was for 6 people btw before I get attacked) because he of 'COVID' and the newborn at home even though they've had people in and out of their house and they've been out every weekend with the newborn. Fine, I left it but I was really upset as I wanted DD's cousins to be there. She has been really spiteful towards my DD quite a few times, excluding her out of parties and talking badly of her purely because she wanted to be the first to have a girl but we ended up being the first, not a big deal imo. We've been to see MIL today and I asked if she's sees the baby this week and how are they doing as I'm not getting a response. Only for her to say 'no, not been yet but going tomorrow as X is having a halloween....' and then she stopped talking. So I asked 'Halloween what?' And she completely ignored me. Turns out BIL's girlfriend is throwing a Halloween party for the kids in the family tomorrow but DD wasn't invited. I will no doubt see pics on Instagram later on in the week though. AIBU to be pissed off here? I haven't done anything but be nice and helpful and my 2yo DD doesn't deserve to be excluded and left out just because they seem to have some sort of a problem with me for some strange reason.
