FIL is getting married this spring to his mistress (only mentioned as background and as she loves to cause rifts)
We have been civil to her throughout their relationship despite the issues she has caused as we wanted to be the better people and allow our children a relationship with their grandpa.
We don’t support their marriage based on how they became a couple, but DH wants a relationship with his dad. If he doesn’t accept her then his dad will go NC. This upset DH as he was very close to him before so he keeps quiet to keep the peace despite his mum’s feelings, they assume we are happy for them as we keep our opinions to ourselves.
OW has been friendly enough, but slowly in the past year she has been segregating our children. DH has a DD from a previous relationship and we have 2 together. OW has sent DSD an invitation exclaiming she will be her bridesmaid. She’s 9 and very excited. However the younger two haven’t been asked and are aware OW has left them out. They’re almost 7 - twins. They have seen DSD bridesmaid dress in photos and are upset they won’t have the same ‘princess’ dress. I’m livid that she’s leaving out 2 children and that FIL is allowing it.
AIBU to refuse to go to the wedding? DH will still want to go but I don’t think it’s fair for my DDs to be subjected to favouritism. FIL states it’s up to OW who her bridesmaids are and he won’t get involved.
This is the first time I’ve let it out after holding it in to keep the peace, but I’m sick of this woman causing divides. I’ve been friendly to her and never expressed my disgust, but I’ve had enough. I wish DH would tell them all to F off tbh and defend his children instead of wanting an easy life.
WWYD from here on out?
