Boys are confusing??

Kirsty • 18
Why are boys the most confusing thing known on this planet? I am currently speaking to this boy and I really can't figure him out, I don't know if he's in to me or not. If I message him,we speak for a bit but not for long but then when I don't message him or speak to him, he gets mardy because he says he wants to talk, what does this mean????
