Sometimes what people love in us, what attracts them, is the spirit of God in us, because they're thirsty for HIM and are drawn to us like wounded souls to a physician. It is very important to put ourselves out of the way, in order for the Lord to use us as vessels and minister salvation to that person. Ego must totally die and Jesus alone must have freedom to operate.
I encourage you, my dear, to become obsessed with her salvation, to fast and wail and plead for her to know the Savior. If you win her to the kingdom, you will have shown her the greatest love there is. Try to ignore any romantic aspect and put her salvation as your number one priority.
See her love for you as a great opportunity to "trap" her lovingly into the arms of the Lord Himself, and as you do that, the Lord reminds you that when you seek first His kingdom and righteousness, then all other things shall be added unto you.
God loves people so much, He yearns so intensely to save them, that He will use anything about us to draw the lost unto Him.
God bless.
