I have known said "friend" for about 4-5 years now. We started off best of friends, the drifted apart, but more recently have been a bit closer. Anyway, we know a person called E, who I used to be friends with until she backstabbed me (another story) about 4 years ago. We don't speak, but have attended other mutual friends functions in the past and managed to avoid each other. Said friend is very close to E. Said friend got engaged over the summer and is getting married on Good Friday. Just found out through another mutual friend that I have not been invited to the hen. When I questioned said friend about it she said since E will be there, she wants to "keep the peace". Are we 12? E and I fell out years ago. I could care less about her. I have managed to ignore her in the past, why not now? AIBU?
