MIL is on her own and DH is her only child. She has always been overbearing and very demanding of him, financially and emotionally. She isn't a horrible person at all and she is a loving grandparent but is definitely enmeshed with DH and this caused issues when our first DC was born 7 years ago. After having children DH started to prioritise me and the children more, in only a natural way he still cares for his mum a lot, and this caused resentment from her.
Things we did she didn't like - moved 20 miles away (couldn't afford to live where we were previously), he stopped paying a lot of her living expenses but had given her a lot of money we couldn't really afford in the past. I admit I resent how she was/ is with DH - expects to be wined and dined at least once a week and has told him that she prefers time just the two of them. However she is always pleasant when she sees me.
She has wanted to come on holiday with us since the DC we're born (7 and 4) and DH has said he feels he has to do it "before she dies". She's 67 and in good health but tells him often she thinks she may die soon. She openly asks us to take her on holiday but says she can't afford to contribute a single penny to it. DH wants to take her and I feel I can't say no as it's important to him and I've told him it won't be a regular thing just once. I am not happy about it as I feel a bit like the third wheel with them at times as she simpers over him a lot and feel like she just tolerates me.
Sorry finally getting to my point - DH tried to sell it to me as childcare whilst we were on holiday, I don't really want or need it but I guess a dinner together would be nice, but he also said that whilst on this week's holiday one night he would need to have a dinner with just his mum as well whilst I would be with the kids as he would have to take her for dinner the two of them at some point. I feel so uneasy about this for some reason. They go out for dinner the two of them at least twice a month and I don't mind in the slightest but to actively leave me out on holiday (a holiday he and I are paying for) just feels galling.
AIBU?
