So, there seems to be some conflicting attitudes about cheating here, at least among the guys. Some people seem to think that a guy is not culpable if he knowingly sleeps with a woman who is with someone. Others hold both people equally culpable. I'd like to see who thinks what, and get explanations as to why you think that. Personally, I think both people are culpable. If you help someone cheat, you are as much to blame as her. I'd be mad at both people if my SO cheated with some guy, so why should I make some other guy feel the same way?
