I have stayed friends with my first boyfriend. We went out for six months nine years ago. I haven't seen him for a couple of years but we have stayed in touch on Facebook. Recently we bumped into each other at a club and said we should meet up for a drink to catch up. My DH was jealous and against this. He would be welcome to come along so could see there's nothing going on but he doesn't want to because he doesn't like my friend. Then my friend said he might not be able to meet up because his wife is insecure about it. Again she would be welcome to come along. I am disappointed and insulted that people apparently think I would be unfaithful. AIBU to be friends with my ex or are our spouses BU to be against the friendship?
