There is a guy I like, and he kno's I like him. He likes me back (or so he says). We usually email, but lately he hasn't replied to anything I've sent. We don't act all "lovey-dovey" we just act like good friends, so I don't think I'm coming on too strong. So I was just wondering what you people think it is and what you think I should do. And thx~

Ask him what's going on. Nobody can tell you better than himself. If he tries to change the subject or gives you an "I don't know" answer, then the odds are that he isn't being honest. Hopefully you two are close enough that he will feel comfortable telling you what is really going on. I believe it's better to know the truth, than to go on wondering. So brace yourself for an answer you might not want to hear.

Ok I'm guessing this is a teen romance... With that in mind let me tell you - boys are not good at discussing their feelings - once again - boys don't talk well about what they feel. This is especially true if the feelings are particularly strong... Don't be deterred by his off handedness just be yourself and try not to assume you know what he's thinking. Often boys heads are pretty damn empty or just filled with boobs beer and cars and boobs... you get the picture. Good luck.
