Does giving a guy the silent treatment really work?

So me and the guy I have been talking to are on a break. I want him to realize that he has a great girl and that he should appreciate that! I wait for him to text me, I never text first. In the beginning I never told him I had feelings because we were just having fun and that's when he fell for me. Should I just be silent to all the things that are on my mind like before? Of course be nice and confident when he does check in. Or if something is bothering me let him know it! Or wait for him to bring up that convo? MEN I NEED YOUR OPINION! Thanks!
