AIBU to feel put out by my ex visiting my parents at their house after 10 years? In a nutshell I left ex 10 years ago gone through an unpleasant divorce lots of anger and demands/restrictions from ex. Over years just ignored each other but never crossed paths until big family party this year (kids together) everyone was on good form from hellos to small chats! First time for both sides in 10 years! My side amicable some of his side didn't come because I would be there! Anyway I found out this weekend by someone else in the family that my ex visited my parents - I didn't know!! and finding out feels like a betrayal I'm all for politeness, keeping amicable and small talk but going around houses just feels like an invasion! Don't know what to think - bewildered
