LGBT: I like this guy but he's already pissing me off?? What do I do?

If your relationship manages to progress past its current state, you are still going to experience this. Right now is when people should be texting and calling like crazy...it's still that fun, initial part of dating...and he's not doing it. It doesn't mean it doesn't like you, it just means he probably doesn't like texting/calling all the time and probably also likes having time to himself. If this bothers you (and it really seems it does), then you need to move on because your personalities don't jive.
