Calling ex-boyfriends

I almost called an ex-boyfriend of mine tonight...just to check in. And I realized, that I have been systematically revisiting every guy I dated to see if any of them could be and are worth reactivation. Anyone else thinking about retrofitting your present with a past relationship? It all started because a dear friend of mine, M, recently broke up with a real jerk after three years of dating, he called her and dumped her OVER THE PHONE, quite unceremoniously I might add. Then, proceeds to call her after a certain time, lets say two or three months, to let her know that he's seeing someone. This prompted said friend to go down memory lane and start thinking about better, younger, times with her high school sweetheart. She called him to "see what he was up to" and it quickly turned into a rude awakening. Much to her surprise, he was indeed happy with out her, with a woman he'll probably marry and no, he didn't want to see her. So I thought twice about going back down the same road she did, but I can't say I wasn't tempted. I'm getting older...and I can't remember the last time I had a real date. C'est la vie. My heart tells me that it's better to wait I'll find along the road ahead, rather than poke around in the dark alleys of my past, but my head says...it doesn't hurt to call one or two of those ol' boys, because hey, if you can deal with a little rejection, nothing ventured nothing gained. But I don't think that's M's impression.
