How would I feel if I was being cheated on? Well for one I would realize its not the rest of the worlds responsibility to not sleep with my partner so he cannot cheat. Of course people shouldn't go around sleeping with married people but in the end the person in the relationship is the one holding the responsibility and the one who can make the choices that will effect your relationship. Is it a strippers fault when a married man pays for a lap dance? No. It's the partners fault for deciding to do something that is not o.k. with his partner. Again, I don't agree with sleeping with married people but I certainly don't agree that the third person has anything to do with a marriage or relationship falling apart. Only two people can cause that to happen and thats the people in the relationship.
