What ways to show my crush I’m interested in him without fully admitting it to him?

I want my crush to make the first move. Im too shy and scared of rejection and I feel like he is too. Some days I feel like it’s a one sided crush and he just friendly to me, other days I feel like it’s mutual. I want to show him a sign or something that will allow him to make a move. What should I do?
