Girls do you ever tell the guy YOU LIKE that you dont like anyone?

There's this girl we've been friends forever, one of my closest to that point. SHe would always help me with my relationship problems with my GF. She would ALWAYS be there to hear me out and i would do the same for her. At first i liked her a bit and asked her who she liked but she said she didnt like anyone =/. soooo i decided not to (initiate any romantic feelings for her) but after I broke up with my gf she was there for me again and one day she even pulled a prank on me by asking me out, i went to her bestfriend to ask what to do cause my feelings were supressed for her due to what she said, but she was smartrt than me and told her bestfriend just in case xP (i got pwned) i said IDK ill have to think about it... caause i liked her but i know she doesnt like anyone... then she called me and started crackig up and saying it was a prank =/... I hung out with her a few times, she asked me to study with her and i tell her to jog wiht me... and when we talk we could talk endlessly even through IMs our convo was from 7:00pm to 12:00am idk is there a chance she doesnt mean it when she says she doesnt like anyone? do you think theres a chance she likes me =[?
