I tried it, he was a good guy, I didn't fall head over heels for him. He attended my graduation, we were cool. When I told him, I was gonna move to Florida, he distanced himself from me and finally called me up drunk saying he didn't have the guts to stop me, but he loved me.
I told him to go to bed, and supposedly it hurt his feelings.
A year later, he had married and knocked up some other chick, and he hardly talks to me.
I've met some guys on AFF before, we never had sex, messed around and flirt, but we're still super great friends. And I met them at 19, and we still frequently talk.
