How do i get through to my husband?

I really need some marriage advice, before I convince my husband he needs to see a therapist. He had a traumatic childhood. We were friends in high school and started dating when we were 16. The problem I have is he is a bit of a push over. His whole life everyone has pushed him over including the people who are supposed to love him the most (his family). His mom took off when he was 3 and came in and out of his life starting at about the age of 10 even to now. She manipulates him, and always seems to get her way. She hasn't really done anything to me for me to be upset, we don't have a close relationship. What I'm upset about is that I hate seeing him hurt. She comes in and confuses him and I can't just sit back and watch anymore. I love him and he doesn't deserve that treatment from anyone. She tells him how terrible he is when he doesn't give in, and that's wrong, he's done nothing wrong. I just think I'm a terrible wife for allowing someone to confuse and hurt my husband this way. I've tried to bring it to his attention, but he doesn't see it. And he runs off angry, I'm not screaming or doing anything to induce anxiety or make him feel "uncomfortable" (I guess is the word to use) What can I do? Just let him figure it out or step in? She just has to be in control, and were adults. Nothing is about her anymore, I guess it never was, but... our only concerns of happiness should be his, mine, and the family we are trying to create. If he would only see (as I am saying) the only person you need to worry about making happy is yourself, life is short don't do anything you don't want to. Because I have heard him say many times "I just want everyone to be happy."
