If he already has a divorce lawyer and is pushing you away, his mind seems to be set up. It takes two and he is not willing to go to counseling. I agree with those that think separation is a good idea. Maybe he will realize how it is to be without you and try therapy, or maybe you realize you are just as happy without him and can show your daughter a good example of confidence and independence. I know it is easier said than done. Best to concentrate on the transition for your daughter. I would not know to handle this. What does your therapist say?
