SIL is having a birthday meal but I can't come because when DH asked if me and kids were invited she said "restaurant isn't suitable for kids" knowing full well that would result in me not coming because I have no other childcare where I live. What is strange is that she said to me last weekend that she'd see me on Thursday, which is why I got DH to check. So i'm thinking its potentially more MIL influencing the situation and i'm uninvited. And feel a bit hurt.
Backstory: MIL and FIL fell out with me a few months ago because DH told them my parents had found them rude on one occasion and instead of being sorry they lost their shit. Around the same time MIL was rude to me about party planning for DH bday, and so I told her very politely to not worry about catering for DS bday party. The truth is I'd had enough of her controlling, critical nature. Anyway all hell broke loose, with MIL crying at the door to DH saying batshit stuff like "she (me) is taking the grandchildren away from me" and "you always side with her" (duh) and "she's so spiteful". Never once did I say a thing to her. And since then i've had her in my house twice, and just last weekend was over playing happy families at hers! Ironically for SIL's birthday. So I feel like this was pre planned and I was never invited.
YABU - you're being dramatic its nothing
YANBU - she/MIL doesn't want you there
