I'd go as far as to say that it's a form of mental abuse OP.
If he genuinely wanted to make sure you were alright he would allow you to move on, by keeping a formal arrangement with you regarding the DCs, so you could adapt, heal, and move on.
This man has made it clear in voice, that he has no intention of 'coming home' and having the label of someone's Husband. He's quite happy to hold all the cards. He gets both worlds, daddy and man on the town and his ego stroked to boot
He knows explicitly how much you want him, you've told him, and he has said he doesn't feel the same.
But he comes round daily, lets you have what you want so much for a temporary fix, shows concern, and gives you just enough to enjoy that routine and then picks up his jacket and fucks off back to the single world, and leaves you there alone.
And he does that to you every day.
What an absolute disgusting bastard, can't you see how cruel he is being by doing that?
