It sounds like you had a nice weekend and got a great deal accomplished. In regards to your h saying he can't sleep with someone unless he cares about them, I'm not sure what to say to that. My h says that same thing and slept with someone he met on snap chat 3 weeks after moving out. Did they have a deep bond? I have no clue, although 2 months later they say they are in love. I can't do anything about it.
In regards to sex, that's your call. My m was SS so for me I wanted to show h that I was committed to changing that and saving the m. I knew it wouldn't change anything so I didn't feel bad or used. I felt like I could say I tried. Do what feels most comfortable for you.
We all know actions speak louder than words. It's impossible to explain the inexplainable so keep going to anger management and divorce care. I went to divorce care and will go again when it restarts in August. Keep focusing on you and your child. Sounds like you are doing some nice work on yourself.
