The thing that Ive really hated the most going through this experience is right there in your last post. That feeling that the WS gets that we, the LBS, are their ENEMY. That feeling that they express that WE have been holding them back for years, that we have made them SO incredibly unhappy, that they HAD to go out and find someone else.
There is nothing you can do about it, but take away their need to see you as the enemy. Stop feeding them reasons to hate you. They have plenty built up in their mind already...no reason to add to them. But, we still need to protect ourselves - so sometimes we have to choose.
What you need to remember is that this...all of this...is not about you. Its about HIM. It never was your job to make him happy. It is his job It always was his job. And he will learn that sooner or later.
So for now, keep your focus on you. Follow the steps in DR. Youll come out on top with or without him.
