I won't go into much detail as SIL knows I'm on here but I really need others help with coping with SIL's relationship with me. For reference, SIL is DH's brother's long term girlfriend. I've always had a gut feeling she didn't like me as much as she pretended to in front of other people though I can't explain why I've always felt this way. SIL gave birth to her second born in august which happened to be 2 weeks before my DD's 2nd birthday. She banned her first born from coming to DD's little party get together with her cousins, her excuse being 'Covid' when they have a newborn at home which was fair enough. Until I found out a few days later that ever since she gave birth, they have had friends and family coming in and out of their home to welcome the newborn. We were never invited..(we still haven't met the baby). DD never even got a birthday present or a card from BIL and SIL. She then decided to start some drama where she told MIL that we've not bothered to come and see their newborn and we've been ignoring them re texts about DD's birthday card. When this got to us, DH got in touch with BIL to see what that is all about it and what texts she means because we never got any to which BIL said there was no texts, it must have been a misunderstanding
and they will leave DD's birthday card at MIL's. This was in August. Asked MIL a couple weeks back, she said they never left or mentioned anything. They've seen her plenty since then. Fast forward to yesterday, it was our niece's birthday and I've just found out they had a zoom party with all the family and cousins, except DD who was never invited. My heart aches for DD. I know she's only 2 but she hasn't done anything wrong and they seem to be singling her out and even though DD never even got a card from them, we still dropped a card with some money round to MIL's for her to take to DN when she sees her on her birthday. She said she gave it to them yesterday. Should I just stop trying? Should I put a stop to all birthday/Christmas presents and party invites? I know MIL will have a problem with this and will try to lecture me and make me look like the bad guy again for deliberately leaving DN out. She always has double standards when it comes to us.
