Guys, what should I do?

Some people aren't into FB or texting, don't worry about it. If you have a number of signs that he likes you than I'd guess he would. Guys like girls who aren't needy, or who come off to strong (well I do anyway), if they are needy or come off to strong I can't help but think they are a nut case. Give him something to chase you for, get him involved. If you want to talk to him more, try ringing him up, of course you should have something to talk about, a reason, but it might help. Also do things that may help him to think about you, to remember to do things with you- WARNING though; of he forgets it could make you feel pretty lousy, or rejected- be careful. Don't look to much into the FB or texting thing, he wouldn't be!
