I am glad your Son is no longer being used as a weapon against you. I remember how heart sick that was making you. I am glad you have made progress to some extent.
I do wonder if it is possible to brush aside the negative aspects of your life and all the emotional baggage it has created and just concentrate on the good. Or if you have to deal with the negative aspects to allow the relationship to become good.
And regaurdless of what you have done in the past Heather I do not believe that you deserve to be treated as you have been. Your A was not the cause of your unhealty relationship it was a symtom of it. Your H needs to face up to that just as my H does.
