Tell him you are miserable and want him back it might get things started.

I'd say give him some time, like a month. No calls, no texts, no nothing and focus on yourself. Do things that you love and get in shape. Then after that if he doesn't reach to you, you try to, by sending him a casual text and then another one and then try to make him invite you out and then you flirt a little and remind him why he liked you in the beginning. Just please don't be pathetic and beg him or anything because that will push him away more. Be cool and try your best to make him realize what he lost. That's what I'm doing right now, I'm going exactly through the same sht... good luck!
