Fact: Mr. McCall is an alcoholic

http://alcoholism.about.com/cs/abuse/a/aa990331.htm

Basically, what in get from that link is not all alcoholics are abusers, but most abuse is alcohol related. It is possible for him to be abusive, and Melissa to understand it was the alcohol, and to care for him still especially if he is clean, even if she can't really ever trust trust him again.

And please note, I'm not even sold on this theory, and I can see where it's coming from.
