You play this wrong, and she will find you weird and creepy. You need to flirt with her. Flirt. With her. Flirt. With. Her.
If she does have those feelings, she will flirt back. This is the only way. Nothing else you do will get the message across. Buy her dinner? You're a great friend. Change her tire? You're a great friend. Go with her to the hospital for grandma? You're a great friend. You need to send out tendrils and see if she responds at all. If she doesn't, then you know that it's a lost cause and you can stop before you lose her completely.
You want to be one hundred percent sure she likes you before you do anything. That is never going to happen. This doubt is here to stay until you find out the hard way. FLIRT.
