I NEED ADVICE.!!!!! will this make it or break us....

So my partner and I were getting pretty serious right before prom and the night of he ditched me half the time for his friends I tried not to let that ruin my night but now I'm thinking back to it and I feel so hurt I don't if I should confront him about it or just leave it as is. He did say he was going to make it up on a date but can your really make up a big night like prom? ... I don't think so... what should I do I want him to know I'm annoyed but I really don't want to talk to him. I also felt as if he didn't want to be affectionate because he didn't want people to get the wrong idea? But afterwards we kissed in front of his friends Idk 😐
