Love my friend but she says she loves somebody else?

I have been friends with a girl from the past 3 years. she has been my best friend. we have been very close friends actually very close. we have gone physical also some times. I love her a lot. But i never dared to tell her. Now she says that there is someone special friend in her life and I am just a normal friend. But even today for anythign she needs me. Dont know whether I need to continue or not? I love her a lot.
