She shouldn't, I mean that's really shitty if she's agreed to marry a guy and have a monogamous relationship with him and then goes back on that and has sex with other guys. Cheating is horrible.

Of course she can. If her husband doesn't like it, he can end the marriage. It is ethical? Depends on what she promised before the marriage. If she promised to be faithful, then she lied. Or maybe she was sincere but the marriage isn't important enough to keep that promise. If they don't have children, I don't think it's a big deal -- lots of marriages don't work out.
