If platonic friendship with her isn't valuable to you (if you stopped talking to her when you learned she wanted to be just friends) then you do not 'love' her. You just have a crush on her.
Take some time apart, and your crush will fade into nonexistence. Then you can restart the friendship, if you want to.
Be aware that she will probably never find you attractive, sexually. That's what women mean when they say 'friends'. They mean someone (male or female) who they like a lot and hang out with, but are not attracted to. I'm sorry
