No because I'm not an idiot.
I'm also not dumb enough to get involved with a guy who already has a girlfriend.

I swear common sense is lax.

because she's a dumb fuck with false hopes.

I wouldn't. Forget the third, two strikes and you're out. But if I knew that he cheated on every girl, then it would been goodbye on the first strike, and that's IF I gave him a chance.

Yes be very glad that girl isn't you.

Oh sure, they'll say they'll stop. They say they've changed. That they love you and only you, that you're the one they want. But it's all lies.

In my experience, if he's cheated more than once he's not going to stop doing it now so get out while you still can. 

@misswonderj@xanga - hah! amen.

Judgments aside (since I agree with everyone above), perhaps she really just doesn't mind? It's a stretch, but perhaps he provides her with important things that she needs, and she really doesn't mind if he shops around for sex. Eventually perhaps they'll simply realize what he needs is a girl who's willing to have an open sexual relationship, and perhaps that's her. 

Now, more likely she's delusional, desperate, a sucker for believing what I assume are lies that he tells her that he won't cheat anymore, some combination of all 3, or other things. Maybe she believes she's not worth being committed to. Maybe she thinks she deserves to get cheated on because her self-esteem is so low. Maybe she's just holding onto him while she waits for better. Maybe she's just using him for another reason (money, housing, etc). Maybe it's just convenient to have him around, regardless of whether he's 'faithful' or not. I could keep going on and on... but most likely it's that she believes his lies and she has low self-esteem.

Wait... and how is it possible for him to try to hook up with you when she's in the same room??? Maybe same building? I mean I can understand if you try to hook up with a guy under a blanket while his roommate is rockin out to guitar hero, or something...

@iwasjustthinking@lovelyish - Not to just sound contentious, but it means he's not fulfilled sexually (at the very least). He might actually be quite happy with her in many other aspects, possibly even including sexually. While the guy is clearly a douche bag for cheating, on top of that he's probably just a horn dog who wants to hump everything that moves. It doesn't NECESSARILY reflect on the other girl. I think that's a big problem with girls. When some @$$hole treats them like crap, cheats on them, yells at them, or even hits them, they think somehow it's their fault. They feel like the actions of a person like that devalues their self-worth. That's not always the case. Sometimes he's just an @$$hole.

Furthermore, she may believe that staying with him and 'being a better girlfriend' so that she 'won't drive him to cheat anymore' will allow her to regain her self-worth. "If only she can be good enough" then he won't cheat. Because he doesn't WANT to cheat. Obviously, because he says so. Obviously this is trash, but a lot of girls think this way. It's sad.

Wow, false hopes like crazy. If the guy has cheated on every girlfriend he's ever had, that's the biggest red flag on the face of the earth. It's not likely that he's going to suddenly change. The fact she has taken him back when he done the same thing before is even worse, because now she knows that he's not going to quit. Talk about no common sense. Well, maybe she just wants to be "in a relationship"; you know, until she finds someone else.

I would most likely not date a guy that's cheated on every gf he's ever had. On the other hand, I'd have to give him some credit for being honest, at least. If I REALLY liked him and trusted him (I probably wouldn't), then I'd give it a try. But one slip and he's gone.

And people that go back to cheaters...well, that's their thing. My first reaction is to call out stupidity but hey, I've never been in their situation.

I am so not going to date someone who is a cheater. I believe I deserve someone much much better. If he has cheated in every girl he's dated, then there's no guarantee that he won't do the same to me. And people that go back to cheaters are simply stupid.

no. girls who may consider it probably want to change him for the better. the guy probably has personal issues to resolve on his own.

Were you hoping she wouldn't so YOU could take him back?

Your response shouldn't have been "You have to choose between us." It should have been "see ya."

I'd seriously reconsider dating anyone who ever cheated, period.

I think people go back to those who've cheated on him for a simple reason. You develop the sense that it's something about you that's flawed, instead of the cheater. So, you reason in some fucked up logic that that's all you can really do, and expect.
