Should I go for it?

Jess
I just recently met an older man (I'm 22 and he's in his 40s). This isn't like me at all because I normally wouldn't consider seeing someone that much older, but I'm really into this guy. I can't stop thinking about him and want to see him all the time. I wasn't really into him until I got to know him a little more and he was super friendly with me (holding my hand, being a gentleman, etc.) I don't know if I should go for it or attempt to and look stupid if he really isn't into me. Any ideas on how to see if he's into me without flat out asking?
