You were her friend and it was cool. But then you caught feelings and she obviously never had feelings for you. There is nothing you can do, other than to learn this lesson and next time, with a different girl, push things towards sex right away, never confess your feelings, you fck and pull back and fck other girls, have several girls that you spin as fck buddies. Girl that sticks around and pursues you can be considered as your girlfriend or even future wife, others are for practise.
Read your girl's actions literally - 'I do not like you sexually and I don't want to fck you.'
Get over this situation in your life as a man, nothing really to get over with, be thankful you asked for advice here and not on femenist and white knight forums, they'd suggest you signing sirenadas and buy gifts and orbit her behind for years while she fcks other men.

Book of Pook.
Healthy relationships between a man and a woman is when man fcks the woman, and the woman pursues the man because she knows he is the one.
Unhealthy is what you had, friendship, you like her, you confess, she says no we are friends, etc..
In your current situation, friendship is over, don't hang around a girl that befriended you. All her girlfriends would look at you as not a sexual, asexless material and a nice guy. Run!
