An old "friend" who turned all your other friends against you 10 years ago reaches out and wants to meet for lunch. Do you go?
No. I've moved on. If they want to apologize through email, fine. But I'd have no interest in interacting again.
I would go - its important to forgive - trust is a whole other issue - but I would try and forgive
I can remember a few people from my past who I have no interest in meeting. I may accept the invite and then just not show up as a little pay back.
