Invited to a wedding in April that is next August. Invited by a friend who I used to be quite close to and who set me up with my now ex boyfriend. Groom is ex boyfriends best friend. Group that is going are all friends that I made through ex and none have really bothered with me since we broke up in January. No longer get invited to things. Wedding is a short flight away, everyone going for 3 nights and staying in same hotel. I just don't want to go. Im not part of the group anymore, I'd feel like a desperate hanger on, I still love my ex and us trying to be friends hasn't worked. I can already picture myself sat at wedding table alone feeling awful hundreds of miles from home. AIBU not to go? And how do I tell herP
