Im not surprised you’re hurt @haveiwokenup but it sounds like your DH is hurting aswell. The whole tone of your thread is that you’re not attracted to him, you’re reluctantly trying not really for him but for the sake of his daughter.
I’m assuming he was drunk when he made those comments, and while the comments about shagging your friend are vile, I’m guessing his self esteem are probably on the floor and perhaps he knew these comments would get back to you. But living with this attitude from you must be crushing:
There’s also zero attraction on my part, I don’t find him physically or sexually attractive and haven’t done for the best part of our relationship if I’m completely honest. I recoil when he makes a move on me, so we haven’t got much of a sex life. I try for his sake but there’s nothing there for me.
He obviously hasn’t recovered from your emotional affair - and while he obviously cannot divorce you on grounds of adultory, he’s clearly still holding a grudge against you. If you do make it to counselling you should address this infidelity as well as it is clearly s an issue.
Given your reluctance to give it a go, while objectively it’s completely wrong for him to be hiding money from you and leaving you to pick up the tab, it sounds like he realistically thinks you’ve already got one foot out of the door. If this were a woman in this situation, people would be advising to hide the money because they might need it if their partner is going to leave. I also suspect his looking further afield to move doesn’t mean he’s actually going to do that, it could be escapism /wishful thinking. You need an honest conversation about co-parenting and mutual expectations.
I do think it’s telling that it’s the deception around the money that you are most hurt by - if you were emotionally invested in him I expect the sexual comments and his description of you would be equally if not more hurtful.
Have you confronted him about about what he said? I think you need a really honest cards on the table conversation - it sounds to me like you’ve caused him significant hurt, and neither of you are on the same page. If you’ve really not got any interest in honestly rekindling the kindest thing to do would be let him go.
