At a party I heard that a very popular good looking boy was attracted to me, and I ended up kissing him a bit. We then texted for a couple of days and he was invited to a party at mine tomorrow. He is apparently 'terribly shy' and 'won't do anything unless I do it first', I don't know how true that is because others say if he truly likes you he will text first. yesterday I had to text him first and today he hasn't messaged me at all. I worried that he's got to know me and now decided he's not interested because I'm a bit of a geek. I wondered whether I should be worried?
I think it can go both ways. But I'm pretty sure that by kissing him you have OK'd him so it's pretty strange that he'd still be hesitant about what you are feeling. Dating and all that should come from both sides so if he always expects you to initiate then likely he's not interested. Even shy guys will go for someone if they sense the other person is also feeling it.
