"I Have Known Him Longer"

I have had several women that I have gone out with use the "I have known him longer" as a reason to go back to someone they have dated or to go out with someone else. I have never really understood that. Because they have known the other person longer that makes some kind of difference? That makes the other person some how a more qualified candidate than me? I hate to break this to them but if he was a schmuck then, I doubt very seriously if he has changed any. I really want to let them in on another fact. You were in the relationship and he wasn't. He was only in it because he could play you like a fiddle. Since they have known the other person longer, they should know that. I have found that when it comes to dating, men and women can delude themselves into believing anything. I know I am guilty of that.
