Will a man stand by his woman if she cheats?

We always hear about the men that cheat in relationships and how women have to deal with it and we talk about how bad men are and try to figure out why they cheat and why the women choose to stay with them. What about the women that go out and cheat? How do men deal with and feel about that because there are women out there who are no better than the men we talk about who do these things.
