How should I feel about this?

Last night was my school dance..and as usual I didn’t have a date, but whatever, I like going with friends anyway. Once the slow songs would come on, me and my friends would be all crazy and start swinging around in a circle (lol), while my ex was running around trying to find someone to dance with…my friend Kelsie goes, “Ashlie, turn around. Look at Josh.” Josh was going from girl to girl asking her to dance, and they all said no. We laughed it off and kept dancing, saying We’re doing better than Josh. By the second song, he FINALLY got a girl to dance with him, and he wouldn’t look at her, he would look at me, and stick his tongue out. I just shrugged my shoulders and started dancing with my friends. At the end of the dance, he walked up to me [[and my mom, since she was helping out]] and said “Ashlie, I got to dance with three girls tonight, and how many did you dance with?” My reply was “5, my best friends.” and he goes I meant guys idiot. my reply this time was “none, the guy I like isn’t here and my friends are fun to dance with.” he ran away, then called me that night at like, 12:00. He would keep saying how he can do the Booty Call and I can’t, how he gets more dances..I’m like..okay then. He told me my outfit was ugly. My outfit that night was my teal hollister baby-doll top, flats, and jean capris. His was some white shirt with stains all over it, some black shirt thing that goes over top (like a jacket,it has gray flames, and it was kinda ugly, not to be mean) that he wears to every single dance, because he considers it “nice apparel” Khakis, and black and red high-tops…he’s trying his best to spread the rumor that I’m jealous, but I’m not. What should I do about all this, and how should I feel?? because I feel kind of hurt or let down.
