<human>: Can you succinctly summarize the text in 1-3 sentences?

Hello not sure if here is the correct place to post since i am not in an relationship so i apologize in advance.
I (18M) just got outta high school along with senior classmates. I really like this girl(17f) i only met this year. We get along really well we have no problem talking to each other whatsoever. I asked her to prom but she gave me some excuses that she wanted to go as a group and not "together". Well i got over it and we started talking again. Now she has a boyfriend and its one of my good friends. It felt like my chest was sinking. i found out at a party we were both at they were both at holding hands, dancing together, etc. i had to leave. What should i do. I was thinking about asking her to meet up with me just me and her so i can talk to her about how i feel
<bot>: good friend of mine has turned me down to prom and is dating a good friend of mine. I want to confess feelings although i think she knows what should i do
