I been played

What is the best way to get over a guy who just used you for sex..I only chilled with him twice and both times all we did was have sex first time he started ignoring me right after and when I finally forgot about him he hit up again saying he just randomly cuts people off and he’ll eventually hit me up again when he cuts me off for a little..I’m not trying to be used for sex any longer. I made the mistake of giving in twice but no more..the hard part is im always checking if he’s online and posing stuff. I just wanna prove he made a mistake letting someone like me go.
