i dont know why she do this but shes bitter over something i cant understand
did u guys have some sort of disagreement like either or not to meet a friend?
ask her politely why she does that and tell her how you feel....don't fight ...just let her know with your words that you don't feel comfortable when she does that ...and if she really love youshe should stop doing that....
I'm really sorry to hear this happened to you. Is there a reason that he might have done it? Like a big fight? Please understand that he may be hurting and wanting to vent too. That doesn't mean publicly shaming you is okay, but he may need to express himself too. You say that he shamed your horrible private self, perhaps he feels that you mistreated him? This happened in my last relationship (I was the one that wrote things because he was hurting me) and in the end the trust was so low that we ended up broken up because of it, however, I have also been on the receiving end (I ghosted a guy who made me feel unsafe) and I know how much it hurts. Try to ignore it and move on. If you react, it could make it all worse. Good luck.
