I haven't been here for quite a while. I have a different take on your situation. Obviously, I don't know what's going on in his head.
Assuming you didn't want to have sex much and left him begging - perhaps this is payback time. That you left him hanging so many times when he was needy that he's enjoying not being powerless anymore. The strip joint is just a nice place for him to go and, perhaps, he's struck up a casual relationship with one of the girls.
I haven't been following your situation so what I wrote here is a GUESS. If I'm wrong I'm wrong.
IF what I said is true, you need to strengthen yourself emotionally. He may have little or no pity for you. Perhaps he feels you had little for him at some point. What you need now is respect. Doing whatever he wants won't get it. Don't even think about stripping. Save that for after your relationship is healthy because right now it would be unhealthy for you to do.
My guess is that you're obsessing about this and that you need to spend time with good, supportive, healthy people doing good, healthy things. You don't even have to talk about your troubles with them. Just a smile and a kind word would do you a world of good. If you go to church go to some extra events there. Spend an evening with some friends and LAUGH. If he's at home taking care of your child he's not at the club ;^)
