How can I beat a player at his own game?

Anonymous
There this guy who just happened to be a player. He made me feel so good about myself and it continued when he started flirting with me, ALOT! i thought of him as just a friend so i flirted back but in a friendly manner, then he thought it was time to ask me out which i said yes to and later cancelled. Later on he confessed he liked me and i didn't know wht to do because i had this thought that he was a player so i found something to brush it off..4 months later... i tell my friend about him and he said he knows the guy but started acting strangely after i told him that the guy liked me. He went offline for a while and told me that the guy was a huge player and was just using me which led me to heart break, i guess i had something for him. But now i really dont feel like talking to him but he doesn't know i know about his "game". I want to know a way that i can get him back for wnat he did to me basically beat him at his own game.. thing is i dont know how to do it. Help?
