re: would you date a woman that has cheated in a prior relationship?

If it happened in high school/early college and hasn't happened since there's some leeway there.

But if you've cheated in a relationship after that, particularly in a serious one, I'm not touching that with a 10-foot-pole. Separating from a spouse (even if you can't afford the divorce) is far too easy at this point to excuse any kind of cheating while actively in a relationship.

I can't tell you how many couples I've worked with that tried to mend the relationship after cheating by one partner or the other and it's happened again.
