Should I talk to him?

[919]

Okay so there is this guy who practically every girl likes. He's not like those superficial, cocky type guys though. He's a very awkward, shy kind of guy. But, I'm fourteen and he's sixteen. (He just turned sixteen) I was asking him these questions on ask and our conversation was going really good. BUT. He told me to DM him on Twitter!!!! Like, should I? I'm really insecure at times but I don't want him to know. Also, what if he doesn't find me cute? Plus, I've told him he was cute before on FB but our conversation went nowhere probably because he thinks I'm another girl who just sees him for his looks. Yes he attractive but he has so more to him.. So should I?
Please help !x
Thanks
