Sweetie, you need to read some articles on detachment. Look them up on the computer. There might even be some on here in the archives.

Calling him twice a day - not detaching.
Analyzing everything he says - not detaching
sleeping with him whenever he wants - not detaching

Detaching does not mean move on and go away. It means live you life without regard to what he is doing. Live it for you and your children.

Figure out what your part was in the breakdown of your marriage. And if you feel there are things about yourself that you want to change, work on changing them.

Find out about you.

Detaching takes a long time. It is not easy. It goes against everything you think you should be doing.

But I can tell you that if you dont begin to detach, you are going to push him further away. He is trying to tell you something, but, you arent hearing it.

Don't call him unless it is absolutely necessary. Handle things on your own, as much as you can. When you do speak to him, be light, positive and quick.

You will get this. Give yourself time.
