I don't know that I would call it a set up, but the person sounds like a jerk!
It definitely sets themselves up for the same treatment down the road. What goes around, comes around.
If you know for certain that they've intentionally hurt you, then really that's all that matters. They can deny it all they want, but you know the truth and you'll think twice now before trusting them again
YES! I have been set up! Now I have to join the group!
Are you kidding I'm abused and humilated and told I'm loved and all over again!
