" It may not be something wrong with you but it's probably something you did or wont do that caused him to cheat. If he says that it was for no reason then he's lying. I'm a married guy and I don't ever plan on cheating on my wife but she doesn't allow me to c** in her mouth. She give me head but doesn't let me finish. Now if I was to do something it would be for a reason like that. Not saying that it's right because it's not."
