I fell for this one mf who happened to be my friend, she said she likes me too. But now that we are dating she doesn't give a fuck about me?

We used to be pretty close friends, I know what type of humor sh
e has. I liked her for 2 months but I was sure about it. Me who is afraid of commitments , committed in this relationship being confident about the love I had for her. She said she won't ever cheat, and to trust her. Ik she's trust worthy but after 20 days it all started to seem weird. She always stays with her friends, I don't have a problem with that but she could at least come and tell me she's busy. Im the one who always approaches her first. When I told her about that, she was like my friends are gonna be in different sec or whatever, when we don't even talk five minutes a day. Recently on our prom day, I asked her to dance with me, she said she didn't liked the song, and left. And then I went to her classroom , she rudely said why was I there. After that I checked insta, and found a video where she was dancing with her friend, very happily. I just don't know what to do. It's drowning me out. It will be a help if u guys suggest what I should do

We broke up. It's was like one sided love even tho we were in a relationship. Whatever happens, happens for good I guess.
