Sometimes you really do just need to seek professional counseling on these matters, I'll say that first. Okay... a couple of very helpful books for me were
Courage to Heal (I think the author is Linda Bass... I'll double check and edit - edit: Ellen Bass and Laura Davis!) plus a companion volume that your husband could read as a way of understanding what you're going through (at the time I had no use for that one, so I don't know how it is). I'm also very fond of anything by a lady called Sark. She touches on this issue frequently as well.
It's a tough nut, for sure, and SusanB is right, I don't think there's any "getting over it" at least not completely. I just try to think that everything, good or bad, that I have lived through (survived) has made me the person who I am - and I actually like her, these days, even if she's kinda chubby!
My big source of strength (and come to think of it, I don't know how healthy this really is, but it works for me) is that, when I turn to a habit that I know stems from my fear and shame, I think to myself 'If I do this, HE wins. If I allow him to influence my life and my behavior now, after all these years, then he still has control of me, and I won't allow that.' It has helped me break a lot of destructive habits and problems that I used to keep men and even friends away, so that I wouldn't get hurt.
Anyway, please come talk to us any time you need to, and take good care of yourself. You can take care of the weight when you are ready to, just take care of your heart first.
