What should I do? I think I'm in love with a guy I pushed away?

i think this guy liked you.. but he didn't want to show it incase you didn't like him. He done all that stuff to you because it was his way of 'flirting' you can talk about it.. but after 3years how would you expect to get him back? when he is on facebook say hello long time no speak.. just see what he says.
