What Does It Take For Someone To Leave You Alone?

Ladies, I am confused. Why is it sometimes when we tell a man we're not interested they want to go off? Depending on what kind of person the man is, he could take the rejection one of two ways: just brush it off & feel proud of himself for even trying OR get mad to the point where he feels the need to disrespect you. Then they feel the need to start talkin' about how ugly you are, or how many females they have..well sweetheart, if that's the case, why aren't you talkin' to them? If i'm as ugly as you say I am, why are you standin' here in my face upset at the fact that I won't talk to you? Makes no sense to me. Some females do it to, if they realize a man has just dumped them after bein' in a relationship they want to get all mad & shout out stuff that half the time isn't even true. Such as, "You aren't that fine anyways, my ex was way better than you, you're just a sorry, lazy, triflin', man!" - Then why did you decide to pursue a relationship with that person in the first place? Must we just feel the need to demeanor each other's character every time you get mad at the person? I mean yeah, I USED to do that a LOOOOONG time ago *hehehe* but I grew up..The only reason why I'd start doin' it is because my ex-significant other would do it to me. Thank God I am single now! Lawd know's some men are just too much trouble when you're tryin' to get your life on track. - Ain't that the truth?
