Karen, I have skimmed your thread, I will read the whole thing when I get a chance. I just wanted to tell you it is alot better on your efforts if you remain together and not separate. Once you separate DBing is very difficult.
If you read my thread you will see I have no contact with W and if not for me there would have been none since Feb. So the only DBing I can do is remain dark until she wants to talk to me.
As long as you keep the communication going there is a good chance to save your M. Do what DR says. You may want to give him a little space and just be a friend for a while.
I suggest turn him down sometime when he wants to ML. Don't be readily available to him. Make him wonder what you are doing. Above all don't WA.
Be loving toward him just like you love a child (unconditionally)
