"The urge to do it never goes away."
So I'm listening to NPR about "can an abuser be reformed?" So far the opinion of the experts is, "Probably not. Most of them don't want to, and if you send them to a court program, that just means they stop abusing this one and go on to abuse the next girl."
Then about midway through, a guy named Tom who is an abuser calls in. Yes, he grew up in an abusive family. This guy wanted to stop pushing/shoving/nearly punching/choking his wife, he's ashamed of having done it. he's voluntarily gone to residential programs and anger management to stop doing it. He says it makes him feel powerless. He hasn't done it for five years.
And even he says that the urge to hit never goes away.
When they asked him if he'd advise someone else's wife to leave, he said he'd tell his wife to leave if he wasn't getting help. He calls it "next to impossible to overcome it." And also, "It's something I have to deal with for the rest of my life, so I have to believe that there is a way to overcome this."
Another interesting point: he says he was not a violent person and didn't get into fights before he was married, and had no idea he could be that way.
In related news, the comments on this article on whether or not it's acceptable for a woman to hit a guy (answer: no) are interesting, especially given the number of women who admit to have done it in the past and wish they hadn't.
