So there's this guy I've been Facebook messaging with. He's really shy and anti-social. He replies to me and asks me questions about myself, but he never starts the conversation. For example, we'll have a conversation in the evening for about an hour. Then I'll send him a message and he won't open it (i suppose it's because he goes to bed). Then he opens it and reads it in the morning, but doesn't reply (and I'm assuming that's because he has school). So I mean what does this mean and what would you do if you were me?
