How do I get over him?

Tips on getting over a guy you’ve been in love with for a very long time? Honestly at this point I’ve had enough, but I can’t get him out of my mind. I see him everyday, he’s constantly playing mind games and giving me endless mixed signals. He has said many times he has feelings for me but acts like I don’t mean anything to him and he’d rather go make out with some other girl. But no matter what I don’t seem to give up on him 😔
