Trying to keep a relationship with an ex at a younger age? Umm, heap bad mojo. If a guy thinks that the woman he's getting rid of (as opposed to ending a relationship) is not smart enough to figure him out pretty quickly, he's an idiot.
I work with a lot of guys in their late teens to late twenties. Of course, I myself could never, ever have been this clueless (ahem, cough, cough). Almost every single one of these guys are complete morons about real life, but they are truely lost when it comes to anything to do with women. Egads!, these guys are scaring me with what they think they know about women. I myself never knew that all women had to either be at one extreme end or the other of the goddess/tramp spectrum, and cannot be anywhere else.
One of the few good things about being 50+ is that the thought process has tended to move, umm, further north. Well, at least for the majority of the time. I walk around at work almost all day long shaking my head. If guys like this are our future, our species may be going extinct within a generation.
