I understand about taking care of him as if he were a child--I completely feel the same way--I have since discovered that this is part of my (and i hate to keep using the jargon) co-dependency I thought if he left, things would change to, but I don't know how much they have. Some days seems great where he's done a lot of reflection and thinking and seems to love me and want to change things between us. Other days is a complete 180, where he's just mad at me and mad at the world. I understand now that those days, he's just hurt and takes it out on me. I've done the same thing. You always tend to take out the hurt on those you are closest to.
I am going to see a therapist again. I realize now too how much I need it. Wish I hadn't quit 5 years ago--I just ran when it came to the truth of me.
Your man may need his space too, hopefully he'll come out of it and get help himself. My father was that way... I don't wish his outcome on anyone. He died alone and miserable because he alienated everyone in his life that ever meant anything to him--friends, family, EVERYONE. It's not something anyone should ever have to go through, they just have to make the choice to live a different life.
