meet me in outerspace

Ya know what I just realized? I assume men don't mind being used. That they don't care if you have fun with them one night and then don't call or talk. Maybe that idea was reinforced by a couple of guys but I'm starting to realize that it doesn't go for all of them. Maybe I should be a bit more clear...ya see, I didn't think J and I were going to hook up. I was hoping and then we slept together, but I didn't automatically assume that meant we were together. He kinda did tho. So that's how we ended up together. And some of the guys I've hung out with since then (ohh one whole week) and before him are making me think twice...I don't know how to explain it. But maybe I'm being a little insensitive and should tell some guys that it's only for fun and not for a relationship.
