My H intentionally hurt me quite a bit in the first month after BD. It was the worst of his monster phases, and he felt guilty because he knew he was in the wrong. He even said when he's uncomfortable or something is upsetting or hurting him, he cuts it off. He was trying to cut me off because he felt I was the cause of his unhappiness.
As the months have gone by he still does the occasional monster and intentional hurt, but I think he feels guilty over it. In MC he admits he feels like a bully and he doesn't want to hurt me. He liked that MC would allow us to communicate without him feeling mean or unfair. He's like a broken record "I don't want to hurt you", yet he's the one abandoning the marriage. He also rehashes the past daily, selectively remembering only the bad times and exaggerating them 500%. That I know he does intentionally to hurt me because I've brought up with him in our MCs reccommended Non Violent Communication technique, how much that rehashing hurts and stresses me.
My detaching has taken some of that power away from him. I try to remain indifferent and not allow him to make me cry when he does this. I kinda shut down and tune him out as soon as he starts a rehashing session.
His cycling and pretzeling also leans towards hurting but not as intentionally. He knows how to push my buttons, it's obvious... But I feel this behavior is more from his confusion and constantly changing emotions. And because I feel it's not in malice, I tend to get caught up in the cycling and pretzel myself. This is where I am now putting my main energy in detaching. While I love the good days and when our reactionship shows promise, I also know it gets my hopes up and sets me up for an emotional roller coaster. It's soooo hard.
I also want to chime in that my H suffers from severe depression and uses alcohol as a crutch. He has nobody to talk to other than his alcoholic/junkie twice divorced single brother. The guy is a train wreck. We had to bail him out of jail on our wedding day. He has bankrupted us with his constant begging for money and my H giving in. H also knows this hurts me and still chooses to keep helping his brother. I try and ignore it now since there is nothing I can do and don't want to give H the satisfaction of a reaction.
I don't know what we're doing right now... After last MC session and H now saying he's back to wanting a separation. I know he wants me to give up and let him go. I worry the biggest intentional hurt he can do is have an affair. I'm one of the lucky ones who's MLC spouse didn't/doesn't have an OW. He knows if he does, that's it. I won't give him another chance.
