1) Start calling it what it is: anger.
2) We have always talked about my W's A face to face. We've talked at tables, on sofas, but mainly lying in bed and on road trips. (We have the car to ourselves.)
I didn't have to deal with a WS who didn't do the necessary work, but my W says she didn't begin to feel remorse for at least 5 months after d-day. She didn't start to see her A as just another sordid A for at least 5 months.
I did decide on d-day that I was either going to build a good M, or I was going to D, and I knew building a good M took both of us. I also believed that if my W healed herself, she or I or we might choose we didn't want to spend the rest of our lives together.
IOW, I didn't think I could stay passive. I had to be active. I had to keep on top of what I felt and what I wanted, and I had to ask for what I wanted from my W. She could say 'no' to any request, but too many 'noes' would mean D. Luckily I got a lot of yeses, so I never had to make the choice to D. I did, however, ask myself again and again if I was still on board for R.

So where are you? You're unhappy in your M (I know you're not M, but the fewer keystrokes, the better), but you don't want to be single in your 30s. What the fuck are you doing to yourself?
I'm with Bigger (and the Stoics) on happiness - you can be happy even if your M isn't. But I think even the most stoic is likely to agree that removing a source of unhappiness will ease your way to being happy. If you're done with your M, accept it and move on. You might find someone who gives you what you want and wants what you want to give if you're single. You can't do that if you're M.
Or ... maybe you'd be happy with your H if he changed. Maybe that's what you want. You can't change him, but you sure can ask for the changes you want.
I could be misreading your posts, but I think you've communicated what you want, and your WSo hasn't changed. Maybe taking the risk with a Bigger-type conversation is what you need, something like:
'WSo, I love you and want to make a life with you, but we need to change the way we deal with each other. Etc., etc., etc.'
You might want to have those conversations with a good MC moderating. Of course, one of the issues has to be his A, and he almost definitely needs an IC for that. He'll probably need the help of a good IC in recognizing that he needs to make other changes, too. But from what you write, the A is only one issue in your relationship, and probably not the most urgent or important one.

You say you're not getting what you want from therapy. My reco is to talk with your therapist about that. You might need a new therapist. Your therapist may change methods if you can articulate what you're looking for. If you can't, your therapist may be able to help you figure out what you want.
