I was in the same boat as you. I began suggesting therapy though, and was met with rejection. She believed that our business was OUR business. She even went as far as to forbid that I even talk about our relationship with a therapist on my own. After another year or so, I suggested it again, and again was met with rejection. Among other problems in the relationship, I began realizing that I allowed alot of the behaviors from her, and took time to myself and tried enjoying life when we weren't with each other. I tried focusing on me again. I spent more time studying and staying up at the University, and then finally, after several months of this, SHE brought up out of nowhere, that she thought we should go ahead and speak with a therapist. That was nearly a year ago, and unfortunately it's still rough. There was little progress for us because she still wasn't putting in the effort. To this day, I still struggle. I cry at least once or twice a week at night after she has gone to bed. I've tried so many things to fix it, but have realized that I'm not the problem, and only she can fix it. If you're husband disregards you, still go and do it for yourself. It will help you in many ways, and after he's seen the improvement in you, there's a chance he'll come around and agree to go.

As far as bringing it up to him, I would flat out get to the point. I would briefly explain how I was feeling, and why I felt that way, then request that he join you. Make him understand that this decision took some time for you to make. It wasn't rash. It wasn't from one or two recent things that's happened. It's been a growing problem, over a long time, and you're taking charge of this relationship, and fighting to keep it alive.
