Be as friendly with your H as you can handle without expectation. But ask yourself if these random "touches" are all he can offer as a means of reconnecting, is that enough for you. Do you still want to be the one who does the heavy lifting in the R? If I recall correctly he said some pretty harsh things about how your M happened.
You have a choice here and that's a powerful, although scary placed to be.

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
