Okay, I need a kick in the face or something.

See, me and my boyfriend of two years broke up a little more than a week ago. He cheated. But there's a bit more back story: He was a raging alcoholic, and I've broken up with him a few times. One of those times—when he was at our place and supposed to be packing his things and be gone by morning—I kind of rebounded off of some guy, had sex with this other guy, then came home later the next day and found out that my boyfriend was still at my place. We talked, and got back together. Later on, he found out about the rebound sex I had, and I think that's why he cheated. We weren't a healthy couple, all in all.

We both want to remain friends, so the other day, a week after the break up, we went out for coffee, and we both realized that the feelings we have for each other haven't gone away. There's no chance in hell I'm getting back with him, but I can't resist this urge to have sex with him. And I know the feeling's mutual. So now I'm torn on either to start a sex based "relationship" with him (even though I know in the end it would probably end badly), or just block him from my life, and feel like I've completely lost something. S.R.

If you've ruled out getting back together with him because he's a raging alcoholic, S.R., that's fine with me. If you're not getting back together with him because this relationship generates way too much conflict and drama for you deal with, S.R., that's also fine. But if you're not getting back together with this guy—a guy that you clearly have feelings for—because he cheated on you, well, that seems kinda retarded 1. under the circumstances and 2. given your strong feelings for each other.

Yes, yes: you didn't cheat. Not technically. You two were officially "off again" when you had rapid-rebound sex with someone else; and you were "on again" when he had sex with someone else. But... come on. You fucked someone else during a particularly rough patch and kept that info from him when you decided to get back together. He found out you fucked someone else, and he went and fucked someone else. Now you can choose to view his cheating as an inexcusable violation of trust and a betrayal of the first order, wocka wocka wocka, and conclude that you can never, ever back together with this lying, cheating bastard... or you can choose to view his cheating as a part of your most recent rough patch and round his cheating down to rebound sex, even if he was rebounding after you were officially back together, and get back together. If that's what you really want. And it sounds like that really might be what you want.
