I had/have a similar situation. I finally decided it wasn't for me to know right now and I didn't want to know right now. What he was doing/not doing shouldn't interfere with my life. Obviously we both have things to figure out.
I had to quit worrying about what was going on in his head and live my life. I will know when I need to know more.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
