Search Results: getting a guy more into a relationship

There's a girl in my college i found attractive i like her and after talking for 3 months and becoming good friends i confessed to her but she denied saying she just wanted us to be friend after that i tried to cut off my contact but she didn't stopped calling or texting and insisted to be friends so i stayed her friend as she didn't had any other friend i stayed her friend and after some time she got into a relationship with a quiet guy in our class and earlier after my rejection i asked her is it because she have crush on some other guy but she denied but after getting into relationship with him she told me that she had crush on him even before we become friend and now i feel so bad as she made a new female friend too who support her and her new boyfriend. i feel like i am of no use of her now. now she's not being so friendly like she used to be earlier and when i ask her if she wants to end our friendship she don't let me end things and blamed i always fight with her and play the victim card. we had a fight few days ago so the next day I ignored her whole day but after class when i was going back with her she started to cry and run away i tried to calm her but she said she didn't want to talk and her boyfriend calmed her and later when i called her to check on her she said so many rude things to me i felt bad. and told me she felt bad cuz i said i feel like she was ignoring me and not replying to my texts. so we are in fight and not talking so for last few days she been calling me daily but i am not picking her calls and not replying to her texts. Should I end things with her? or Stay her friend? I still have feelings for her.
