Halloween boy probs?

The guy I really like was supposed to see me last night at a party and we were gonna go back to his res and get downnn lol I really wanted to have sex with him and I dressed up all cute in my costume and I went to the party and asked him where he is and he said a different city?! I was like are u for real?!!! I'm really sad and mad cuz I traveled an hour to get there and made sure I looked fire in my costume and he didn't even tell me ? Then later that night he put a cheeseburger on his snap story and I was like this is what you're doing instead of me lol and a few minutes later he had sent me a video and I opened it and it was this girl saying oh hey Kelly don't worry michael is doing just great he's here with me and we are having so much fun and I'll make sure to keep him happy so u don't need to worry u can leave now bye! And that was so rude like honestly who tf does that?! Idk guys I'm kinda heartbroken and need some support
