When my husband first left me, I blamed everything on myself. Now hubby came back and we are in therapy together. Therapist tells him he doesn't believe him--that he is the cause of the problems and he is running away and not believing that he is the major part of the problem. T has helped me get to the point where you are--you are OK, you have things to be angry and upset about. And you should not be dismissed as you have been. You may need to express your anger better, as I do, but you are likely not wrong to be angry.

Sounds like you are in a lot of pain, but that you are right about what you are saying. Hope things get better for you soon.
