I didn't take my husband seriously until he threatened to leave with our small child. Even then I just went to Gp got an antidepressant. It made me sicker. We dropped the med and the treatment. It wasn't until a new gp asked me why I wasn't on an antidepressant and I got in his face about not needing drugs that I walked out with a mood stableizer. I went to several Dr's and med before getting on an anti psychotic. It was even longer before I discovered I heard voices. A couple of My therapists had to tell me I needed an anti psychotic before even trying one.
I think you need to get a therapist. Maybe get him to see a therapist.
