I don't know what I want.. Can someone help me??

She is my best friend. we know each other from last 5 years , she had a boyfriend after her breakup with him we became more close to each other she said that she loves me and i love her too but now she meet one another guy and they are in a relationship and she told me that she always loved me as her best friend .. now I am trying to make distance from her since I really love her and cannot see her with some other guy.. But she keeps on calling me and texting me that she want me and she is ready to leave him for me.. but I don't want her to do that because anyways she will never love me.. but from inside I really want her back and want everything to become like before but thats not possible.. I am not able to concentrate on anything I am really dippressed.. I am not talking to her for last 4 to 5 days and I don't feel good.. I don't know what I want exactly..

Keep walking away and keep asking yourself if you need her rather than wanting her. If she really loved you, she wouldn't be with another guy, instead, you guys would be together. If you know in your heart that she will never love you properly, then you have answered your own post.

Thank you for your response .. What do you think will I be able to over come her.. because I am in real pain right now.. It feels like I can never forget her..
