It makes you feel like you're crazy. Their "crazy" becomes your "crazy"
It certainly does. My pulse rate increases rapidly whenever the ex calls me. My anxiety and tension increase monumentally and it usually takes a day or so for me to feel normal again. Mild PTSD most likely. That's why I have stuck to no contact for the most part for so long. If I need updates about my daughter I get them from her parents, so there's no real need to maintain contact.
Arguing with people like this, or even defending yourself is one colossal, huge waste of time.
I just agree and say, "Yeah, ok" and leave it at that now. They give up eventually.
