I think he stopped going because it hurt him to see you doing so well. And flirting. And being hit on. That must have been painful for him. I know it would kill me to see my H doing so well--fortunately, my H is doing terrible right now.lol.

You have to get the compassion to validate properly. "H, I understand you want a D--I love you and do not want this, but I respect your decision to do this. Can we go to counseling? or just take a break? or just separate first?" with LOTS of sadness in your tone. And then drag your feet a litte--do the bare minimum, but do what he wants.

Is this how it went, or did you take charge and "beat him" at getting this D moving?!
