If a guy keeps telling you he's being 'mysterious', what does this mean as far as a relationship goes? He doesn't talk at all. He knows this drives me up the wall. I'm not sure if he keeps doing it because he knows it's what makes me keep thinking about him, or he just generally doesn't like me. I asked him a rather personal question, and he told me in a facebook message a week later, after I asked him twice about it. He's not mean. He took me to work on a last minute notice, and was generally cheerful.
I don't know if he's this cryptic with other people. It doesn't seem like very friendly behavior, yet he has a million friends (he's class president, after all).
What do you think/how should I handle this?
