I went out with my ex for 6 years but we've been broken up for roughly 4 years. No children with ex. I'm married with children now. I still have a shared friendship group with ex mostly due to shared hobby which means we sit next to each other at a certain event every few weeks with shared friends. On friendly terms with my ex, he even came to my wedding. However he's now got a girlfriend (of roughly a year) who believes that exes should not have any contact at all. She also shares same interests but sits with own friends at event and the times I've seen her and tried to befriend her she's made it very clear she does not want to talk. I really value my time with this friendship group at a weekend but now I feel like I can't be part of it as ex obviously feels like his loyalty lies with her and I now get left out of messages about where the group are meeting pre event etc. Most recently I found out the group all got together at ex and new girlfriends house and I was the only one excluded. Now I know she has the right to have whoever she wants in her house (and on the same reasoning exclude who she doesn't want) but these people are close friends to me and friends only and I feel sad that I'm being pushed out. I'm no threat to her. AIBU to feel this way?
