So maybe next time he starts disrespecting you, it might be a good idea to tell him that you won't be disrespected and talked to in that sort of way. Tell him that he is entitled to his view of things - and theirs can certainly vary wildly from the truth - but you will not allow him to belittle you.
I said this to him. He didn't apologize, but agreed with me in a roundabout way. He keeps score. He replies with that he knows what it feels like because I've done it to him- which is true- a long time ago and it's something we talked about in therapy. And yet here it is being thrown in my face again. It's difficult getting apologies out of him.
He said we should talk again today, and when I offered to go to his place (as he came by mine yesterday), he told me he needs to work late and so we can't meet.. I'm trying to figure out at what point just shut down communication with him altogether. Every time we talk it just turns him into blaming me and him being indecisive. I'm exhausted.
