Just keep swimming, I love that picture in your sig!

Justdesserts, therapy is, in many ways, based on an individualistic view of human beings. This has positive side to it but also negative side. So when you go for therapy and pay for this professional service, you're the one who is supposed to change, not your family or the world at large. The changes you make will obviously affect people around you. It would have been exceptionally good and nice if everybody is on the same page but sadly this is often not the case.

Your husband may not want to change. It doesn't make him a bad guy of course but he's learned to make it work in whatever system you had going and now you're changing the game, by changing how you act, and so he has to adjust and he may not want to. So that's why therapy can be so tough because on the one level, you have to work on yourself and change things up, and on top of it, it's a journey that can feel terribly lonely.

Ideally, if the way you're changing is both about being more respectful and caring towards yourself but also towards him and other people in your life, it is quite more likely that he and others will adapt. If your husband is only intent on being, say, distant or abusive or whatever, then of course it may not work out and he may want out. But it's my opinion only, but I think most people will adapt when they see the new way of life you've adopted still shows your commitment to those people, except that now you're committed to yourself also and want to replace troublesome dynamics with better ones, so it benefits all parties involved.
