What do it mean when he always come see you?

It means that you are basically the reason he gets up in the morning. You are his sunshine. Without you, he is nothing. It could also mean that he is literally crazy for you. I'm not saying that this is a major problem, but it could slowly, yet surely, become a major issue. It is nice that someone cares about you so much, but like everything, there is a limit. Be careful with this boy.
