Good luck with that relationship.

Douche bags think it's ok to cheat. Real men (and women) know better.

someone watches too much tv...

agree with him!

Well, just head on down to the local bar and I'm sure you can find a few guys that will be happy to initiate you into the Wonderful World of Everybody. Try to kiss him just after you've finished hostessing a bukkake party and see if he changes his tune.

He sounds like a winner

I think something like a third of all people in relationships cheat, but that's not even a majority...so he's just retarded. PS. I always enjoy Doc, Kay, and Cinn's comments :P

The point is, the OP sounds like she thinks it IS a big deal to cheat. and he's just waved a HUGE RED FLAG. If she has half a brain she'll take the warning and at least rethink the marriage, but I suspect she'll still actually marry him, and then be heartbroken when he gets caught doing exactly what he's probably already doing.

Kick his ass to the kerb for sure, or don't complain when he cheats.

That's the "sanctity" of marriage for ya. And they say the gays are going to ruin it for everyone

Actually, you can. They're called open marriages/relationships. Marriage doesn't necessarily go hand in hand with monogamy, although, for most people it does(for me as well), but there are some people who are married and practice polyamory. Marriages are all different, if a married couple want to keep their relationship open and it makes them happy and works for both of them, then why not? Keep in mind, open relationships have to be a two way street, and it's VERY different from cheating, so don't think I'm making excuses for OP's fiance. I'm just saying that it is possible to have the best of both worlds. :P

That's not a very smooth way to tell you he already has cheated on you! Time to kick him to the curb. Good luck finding a nicer guy!
