I think time is the best way to get over it. Whatever you do, spend that time AWAY from him, not in contact. If you try to keep in touch with him, he will put himself in the best light possible trying to make you stay with him. He will make empty promises. He will point out other men who are worse than him (making himself out to be one of the "good guys" by comparison.) He may even try to tell you that all men do the same things he does, so you might as well stay with him because you're not going to find a man who doesn't do those things. (That was the trick pulled in my first marriage. He even recruited his friends to tell me I might as well stay, because the man who doesn't use drugs doesn't exist; no use looking for one. Maybe in their own inner circle that's true, but it's not true in fact.)

What concerns me most is the "50% normal" part. A grade of 50% on a test in school is usually an F. We all, even the worst of us, have some good in us. That doesn't make the bad acceptable. It's not necessarily a healthy relationship just because it's better than the last one. Nobody's perfect, but there are deal-breaking behaviors, and just because someone has some good in them too, doesn't excuse those.
