left for someone else

Alright so about a year ago I talked to this boy and we were going great but then I started this big fight and just stopped talking, but then Christmas day I asked him if he wanted to come over to my house and hang out because we started talking again and became close I guess you could say, well he came over and we ended up making out and then kind off just spent the rest of the time eating and taking a nap

(lame right but I thought it was fucking fantastic) alright so I thought we were good and when I dropped him off I walked him to the door because I like to go around society standards and be a boss ass bitch and take charge. So alright i walk him to his door and he hugs me, it's like this massive bear hug, and then he kissed my lips and then my forehead

and I mean I thought everything was fine, but then apparent 3 days later we're at my highschool gym for a basketball game and I asked him if he wanted to hang out afterwards but he said he was going to go eat with the boys, so I thought nothing of it and was playing in the game when suddenly I'm distracted by him sitting next to this girl, so my coach pulls me because this is affecting my game

, and my friend next to me asks what's going on so I point to them and then they START TO FUCKING HOLD HANDS AND ACT ALL LOVEY DOVEY

and i was honestly crying because I was so hurt

, and then after the game I had to change into my cheer uniform and cheer for the boys basketball game and you know what they do to me, her and her friend PETTY FUCKUNG WAVE AT ME

, and smile real big. Then as I'm cheering they're mocking me and laughing at me and this guy I though actually liked me is just letting this fucking happen

. talk about a hurt guys, I'm honestly so hurt that he did this to me and I don't know quite how to react. What do I do.
