LOL, you deserved worse.. Now, I feel sorry for the gf if she's still with him, that would be the greatest FML of this scenery. Apparently he's getting away with it if she was there to mark her territory like you said.. =/

@88 Neh, I have to disagree there. The third party is just as much (if not more) at fault. They have no connection to the situation, but still choose to go ahead and involve themselves in such a way that will cause pain. I guess that I just think of it in a different way; kind of like... the cheater was tempted, where as the person on the outside *chose* to do the tempting. (And while I absolutely think the cheater should have the strength to resist any temptation, if not the ability to ignore it altogether, I think the third party sucks more for chosing to put it out there, you know?) I know I'm not explaining it well, but I'm sure you get the gist, whether you agree or not. As much as the partner who cheats is a selfish asshole of doom, the third party just seems like even more of a cow. Anyway, OP, I'm going with a few people here and not clicking either. If you didn't know, FYL, FHL, and kick some serious ass. If you knew, then YDI and a hell of a lot worse.

I hope she dumped his lying, cheating ass. Are their men out there who don't lie and cheat? Forget about that d**khead, one, you deserve better, two, you're no ****.

atleast his girlfriend didn't tie you up nude and punish you.

****. you knew he had a girlfriend

die in a fire nice; and simple for you idiots. also i have heard that respect does wonders in a relationship but just a guess you know...

u should have whisper 'i have herpes, careful' in her ears on you way out

If the genders in this situation had been reversed, a lot more people would have been blaming the cheater. If we don't know the situation, then we have to be agnostic about it; it's unfair to kick the OP to the curb, though I agree that if she knew, she should have gotten the hell out.

iDied at #4 Anyway, #1 has it right. If he just outright didn't tell you, then yeah FYL. If he did tell you and you outright ignored it, then YDI

# 97 - We have no way of knowing if the girl even knew about the relationship, and even if she did, it wasn't her relationship to maintain. She has no responsibilities toward the girlfriend. If I found my boyfriend having sex with another girl, I would walk out, break all contact with my boyfriend, collect and return belongings through an intermediary, and never say anything to the other woman. She's really not connected to the situation. If my partner's going to cheat, it could have been with anyone. The fault lies with the cheater. # 107 - The only gist I'm getting from you is that the woman is always to blame for "tempting" the man, who can apparently have no control over his own desires. Would you have the same opinion if the genders were reversed? You said it yourself: "They [the third party] have no connection to the situation." If they have no connection, how can you place on them the ultimate responsibility for the relationship's well-being? The world is chock-full of temptations; there are opportunities to cheat every day. The cheater could've chosen anyone. Why get mad at the third party when the cheater is the only person who's made a commitment?
