Welcome kyli! It sounds like everyone has covered the importance of therapy, so I just wanted to say a few words about your husband...
I'm in no way condoning his action toward you, but I think I understand it. The way you described the changes to yourself, I would be frightened if I were your husband. I would also be feeling confused, overwhelmed, helpless, distraught, frustrated, and unnerved, or some combination of those feelings. He might need to speak to a therapist, as well.
