Hi confused. I'll start off by saying I'm a bloke so haven't had the misfortune to have to deal with a loser like your 'OH' (although I know some blokes end up in the same situation)
I just wanted to say that not all blokes are like this. Most of us care about our partners, put them first and actually realise they are human beings first and women second, if that makes sense. I would tear my eyes out before treating any person, male or female, like you are being treated (but then I like to think I'm a decent person). He is making you suffer every which way he can. And as others have said, he is preying on your vulnerability. He doesn't care when you're not well, stressed, broken-hearted. He'll say 'chin up' and move onto to something suiting him.
I'll be blunt, but not rude, and say that you don't need him at all in any way, shape or form. He makes your daughter laugh? i could do that just by looking at her
He's a shithead of the lowest order and whether or not anything happened on 'that' night you are not happy about it but he won't discuss it.
I spent too, too many years in a loveless marriage and finally left it. Even though there is no-one in my life at the moment I can still live my life how I want, not how someone else tells me to live it.
Maybe you do need sometime alone with your daughter. It may be painful to begin with, the loneliness, but believe me it gets much, much better. Your daughter won't thank you for struggling to keep this non-relationship alive and what are you teaching her? Bend over and take it if it means having a partner, even though the partner is worse than not having one?
You become a happier person and you'll attract a better type of man, one who isn't out to abuse you.
Crikey, sorry for the rant. I wish you luck
