I agree with Irish. Please don't take this wrong, but I don't think your H has done ANY work. You said,"do these exercise or no more coming to the house". So he did the exercises. He did the minimum required. He needs to do the work, and he hasn't. He just did what you told him to do. I don't know what to tell you to do, but I do feel like he hasn't expressed remorse, guilt, or made an effort on his own to move things forward in the right direction. i DO think he will, but you need to stop enabling him doing the minimum.
You are a great person and the point of doing this the right way, is to make it the last time you up in this sitch, not just to fix things for now.
