Hey Amy,
I'm not a guy
but I thought I'd respond anyway. You are ABSOLUTELY right about guys being slick out of college. I've met a couple of players lately and it took a while for me to figure out that they weren't the "nice" guys they originally appeared to be. They can hide themselves really well!!
One guy in particular was so into me from the moment we met that I was sure he was "the one." He'd call and we'd be on the phone for hours. He'd send the sweetest e-mails when he was out of town (he traveled alot for work, too). Then, about 4 months into our relationship, I find out that he's been seeing his "ex"-girlfriend the whole time (who he'd described to me as a psycho chick who stalked him) and that all those business trips were time he was spending with her. So, my advice is: Just be cautious! And good luck
We all deserve a nice guy!
