I feel the same way when I have my D1 at home with me. I hate that my D1 is being shipped to and from her parents place and that she is begining to notice the changes taking place in life.
Although I don't want to get a D, it is happening whether I like it or not. I had to accept it, and when I did, after nights of hurting, I started to feel better.
I think that STBXW has notice the difference because now she texts me 4 times a day, to the point where I would have to put limits on it (not before 8 am).
As for the balance, I think that you have to have very little hope that he would come back, and put most of your thoughts and energy to moving on. As this is not easy to say, it is even harder to do, but it is probably your only chance at saving yourself and maybe (hopefully) your relationship.
