Take it one step at a time. Also remember that this is still VERY much H's thing, from his time without you....that being said, leave it him, be supportive, but this is his thing to deal with as well. You know that.
All in all, I have to say, you are one of the strongest women I know, here and otherwise. I admire you so much. Each time I think I couldn't forgive my H, I think of you....your grace, strength and love.
