MY X did that & it worked for many years. I am a battered woman. It triggered me, my emotions. I went back so many times, he's say Remeber this, we were so happy here, if he didn't get the reaction he wanted I'd get the verbal abuse, I was his property , he was violent as well, throwing things like yours, but he hit me also but he a Narcissist also which made it total psychological warfare. Seems like your X has some of these tendecies cuz Narcs have big ego & get their high by feeding it. So when he upsets u, pisses u off, has any kinda power over u, he's proving to himself he still has that ability, therefore, feeding his ego, getting a high off of it. It's sick but it's true. My X has it bad & would literally smirk as I cried. You should maybe think of a restraining order with no contact & put down everything he's ever done to you. He's an abuser pure & simple please get out now b4 there are kids involved, I was stuck with my X for 14 years, but what if u do go back? My 2 youngest (his) have ptsd from what they grew up watching, & god only knows what u have now from what he has put u thru. You deserve better.
