A while ago a friend confided in me she had kissed and been texting and ringing a man we both know, he is married and we both know the wife ( I don't know her well).
I was genuinely shocked by this and advised she stop seeing him before many lives were ruined as both my friend and the man have children.
This came to a head when on a night out I saw him and confronted him about what was going on, which he denied but I had seen some of the messages, which took the wind out of his sails.
He suddenly disappeared 6 months has passed and I have agreed to do a charity event with this friend amongst others as part of a team. There has been a group created where we can discuss the event and she has added this man to it (my friend is organising the event) he has also suddenly started to like all her social media content again.
I'm annoyed because I don't like him and want nothing to do with anything that may be going on. Should I drop out of the event to avoid the situation all together? A massive part of me wants to tell his wife.
AIBU?
