It depends on the circumstances.

Most likely no, though.

It would depend.. If I knew I would never look at them the same way again then no

If it were a serious relationship, no.....

I doubt it, but there would be a chance id take them back...

Why would you when there are millions of other people in the world that you could hook up with. For people that think that they can't find anyone else then that's just retarded because the odds are in your favor.

No.

Never, thats a breach of trust. I don't care if I get dumped and they said person cheats but cheating during a relationship is a deal breaker for me.

No.

HELL NO!!!! ive seen that!! my mom was dumb to!!!

no, never, if someone cheated on me i could never forgive them, any relationship requires trust, without trust all relationships will fail
