Doormatnomore,
Get counseling before you scrap the marriage. Counseling has saved many marriages, and you just never know what could come of it. It's certainly worth a try; if not just to save the marriage, but more for your own sake that in case it doesn't work out, at least you went a step further than just throwing it away.
I can't blame you for feeling the way you do...but I can see you're taking a little responsibility for it, in saying you "trained" him to treat you that way.
If talking to him (without crying if you can) with logical points and surfacing what really bothers you doesn't work, suggest counseling. If he won't go, that's a bad sign.
