Thanks to all of you for your replies.
I don't get the game stuff, though. It's not like I'd be misleading him or toying with his feelings by contacting him. He's not given indication that he wants to pursue a relationship with me. He's up for casual dating at most. But what's the point is a good question. I guess the point is I miss him and it'd be nice to have him in my life - even just as friends. I know it's not headed anywhere, but it's not like I wanna marry him either. I think we both realize that we aren't "the one" for each other. But if it's true that a guy doesn't value a girl's friendship after breaking up with them, then that definitely makes me think twice about the whole thing.
And Serenity's so right, anyway, I know. I should probably wait until friendship is my only motive because as things stand when I think that he doesn't miss me the same way, that I'm probably the last thing on his mind, and that he's moving on not looking back, well, those thoughts really sting.
