I had a BIG difference of opinion with a long standing friend. Havent spoken to her for a few yrs. After the altercation, I called 3/4 times to talk about it and sent 3/4 msgs...no reply. Fast forward to now, 2-3 yrs on, she books my son to entertain for a big party she was hosting last Saturday. My son accepted and let me know as he recalled the upset between us. 2 days before the party this lady actually messages me to extend the invite to me and my hubby and also added some very mean comments in the invite about the altercation. I told my son and asked if he wanted to read the msgs. He said yes. He thought they were mean too. He went anyway. I feel a real sense of betrayal by him. AIBU?
