I wish I could you a great big hug right now. I'm not good at giving advice, but have been following your sitch. Two of my very best friends are in the same situation you are, the H's never left them or have had OW, but they spend very little time together doing things. My friend C and her H pretty much go there separate ways, do their own thing, haven't ML in almost 11 years. My other friend C2 and her H never do anything together either, he does his thing, she does hers. They have a pet and the pet is more important to H then his wife. She's really at the stage where she could become a WAW and there are days I want to call her H and say wake up! She's going to walk on you....I can see it coming. She's told him many times that she's unhappy but he's ignoring all the signs. My friend P and her H were split but are back together, nothing has changed with them, her H is drinking a lot, being an ass, I think he's in MLC with the way she describes his actions and the way he's treating here. She might walk againg. It's a sad, sad world out there and I guess you just have to live your life the best you can, be happy, and not too needy, and with an attitude of I can make it on my own. Just give up and decide you're going to be happy no matter whay, do your thing, do things that you really enjoy and then see what happens. I bet you could draw your H back to you.
It's his problem right now, he needs to deal with it. I think you worry to much about him and what he's doing, thinking, let him fall asleep on the couch, heck why don't you disconnect the cable service and not tell him. No TV, or would he got to one of his buddies. Instead of him watching sports on TV, why don't you suggest going to a sportsbar and watching the game there, it's a different environment. I don't know if he drinks, but a few beers always gets my H talking. If he lost you he'd lose the best thing that ever happened to him, believe it!
Oh well, I don't know if I've been any help, but I hope I didn't say anything to offend you either. Whatever you diecide I would miss if you left this BB, I really have gotten a lot of insight into things from you and others here and don't where I'd be without this BB.
