I think I'm finally understanding the "detachment" phase of all of this, I'm sorry I'm a slow learner. Didn't talk to him for a couple days and he didn't come home. I wasn't expecting him to come home last night and he just appeared in the hallway while I was cleaning and it scared the poo out of me. I said to him, "Oh hi, what are you doing here?" and all he said was "I thought I'd come home. Is there anything to eat?" to which I directed him to the frozen meat in the freezer, which he could cook by himself. Then I just.. kept on with my cleaning. He started telling me about his weekend plans and how his barber wants him to start doing jiu jitsu (which he immediately said BUT IM NOT GOING TO)... all the while i just kind of responded with mhmm and cool while I cleaned. He kept trying to get my attention and engage me in conversation.
But you know what? I really didn't feel like conversing and hanging out with someone who thinks its ok to just leave and disappear without a word and then randomly reappear like nothing even happened. So I was polite and distantly responsive, but I just stopped feeling like I cared. If he wants to hang out and talk at me, fine. If he wants to leave and say nothing, also fine. I'm just going to keep living my life and he's welcome to participate.
I also have thoughts about if he's going to regret all of this when I leave or will he really just not care and just go on like nothing happened.
I've been reading other posters and it is nice to know that I'm not alone in this and other people have husbands JUST LIKE MINE.
