I think it is a little bit weird that when a man cheats, the "other woman" tends to get a pretty big share of the blame. However, when a woman cheats, blame is rarely placed on the "other man" (so little, in fact, that that isn't even really a phrase that people use). My personal sentiment is that when someone cheats, it is largely, if not entirely, the fault of the cheater. I think that when someone cheats, anger toward the "other" person is understandable, yet misplaced and often a way of avoiding the real issue of dealing with the cheating partner. Dealing with cheating in a relationship can be a big and daunting obstacle, but one way or another, if you have been cheated on, you have to step up and face that obstacle - generally either by breaking up with the person or putting some serious effort into working out your issues (but if you have a better idea, please let me know in the comments).
If you are in a situation where you are given the opportunity to become the "other woman," my advice would be not to take it. Here are my reasons:
- Drama will ensue
- If you think the man is going to leave his wife/girlfriend/partner for you, you are probably wrong
- Even if you are right, can you really trust a man who you know is prone to sneaking around?
