Hi my name is Patricia. my birth date is 3/25/65. will my 17 yr. marriage relationship get worse?

I have moved closer to complete self-actualization(through personal coaching and earning my clinical psychology degree in psychotherapy), my husband has become increasingly more dissociative. I am on a roller coaster emotional ride between wanting to divorce him and wanting to put up with it for our 13yr. daughter. He's a great father, excellent provider, does every household chore while I have been in school, but remains emotionally distant. He has been like this from the beginning of our relationship I could only place my finger on, "he's a hard person to read...same emotion for everything (which is a flat affect) but laughter. I now know he has great difficulty in expressing ANY type of emotion do to an attachment disorder.
