Yes, we can all say,leave him, he won't change, you'll be better off without him, but it misses the mark, doesn't it?.
Because there's be no need for all of this, any,.of this, if he'd just wash up, clean the bathroom, put some clothes away and seem to know what's going on. Not difficult, is it?
So for me, the question is why is he risking it all?
Is it because he doesn't respect you?
Doesn't believe you'd leave?
Because he just dgaf about living to a decent standard?
Because he doesn't understand that it's part of being an adult?
Because he doesn't care that you have to do all the boring shot all the time, and that is gets you down, because it's shit, and relentless, but he's just pleased he doesn't have to do it?.
If you asked him this, actually said to him, I'm at the end of my tether and I'm going to leave over this issue. You can't change my mind, but I want to know why you'd throw it all away over this? What would he say? What would his reason be? (Not the platitudes, oh, I'll get better, I promise, so long as you don't mention it again).
