Re: ontd, would you stay in a marriage if he cheated on you?
HELL NO.

But, I think ultimately I understand why SOME people choose to stay with their partners after.

It depends on a lot of factors like how long the relationship was, if the cheating was very public, why the person cheated, how many times they'd done it before, how serious the cheating was etc, etc, etc.

I think tho honestly IMO that unless the cheating was a result of an unhappy relationship/you have kids, then people shouldn't feel obligated to try and make it work.
Go find someone who won't cheat on you, they do exist.
