How long does it take? It all depends on your situation...I was thinking about my own history...Was married 21 years when we finally D. I think we had been together 17 or 18 when he moved out. My H had been out of the house about 1.5 years when I wrote this thread. As you can see, he was pursuing me but I was fairly detached at that point.
Did you read DB or DR? Remember the "Stop thought" technique? (I think it was called that...) Imagine a stop sign whenever you find yourself thinking of your husband. With practice you will obsess a lot less.
In the beginning for me I took a swimming class and swam laps every morning. It was great for getting that distructive energy out. Only I would remember about him and his OGIRL and then I would swallow water and flounder in the pool! LOL!
Hang in there. You can do it!
