DSS is holding a graduation party at his DM's this summer. He wants to invite all of DH's side of the family as well as everyone on his DM's side. DH and his ex had an acrimonious split and have avoided each other when possible for years. She is a nice woman and I think she would make me feel welcome but I just do not want to go. There is no believable reason why I wouldn't be there. Do I just have to suck it up and go to support DH? Although I think some of the acrimony is his fault? I just want no part in it personally and I would prefer to take DSS out for dinner separately to celebrate. I'm sure you will tell me it is one of those things that I have to accept. I haven't spoken to DH yet to discuss my feelings, I know he won't want to go either but he obviously and rightly wants to put DSS first.
