So.. a friend of mine and I were talking this morning and we got on the subject of relationships and cheating. He thinks that flirting with other girls isn't cheating, even if it involves sending detailed texts and online messages to someone. He also thinks that showing your naughty spots on cam isn't cheating. He thinks it's all "fun", however, he has told me that if his wife had ever done that to him, he would be pissed off. This friend has done all of the above and sees nothing wrong with it when he does it. Now, I don't necessarily think it's cheating, but it isn't right either. Keep in mind that I was on the receiving end of these texts, online messages, phone calls, and cam.
Is it cheating??
