Is this strange or not?

My crush flirts heavily with me at work. To the point where he can lightly touch me or just hug me. But as soon as we leave. He doesn't communicate with me at all. He does have my number but doesn't call or text me. At work he says I can call him or text him anytime I want. But I don't reach out first he won't make the move. Why is this?
