How to know if she has feelings for me?

I met this girl through my friends and she became a friend of mine too. I didn't had feelings for her at start but started to having it now. I think she give me hints but I'm not sure if they're really hints or she being open minded friendzone. She sometimes ask if I love her then when i ask her what she said she says nothing. And she always my play hair and touch me a lot (compare to my other friends). She rarely touch them. She touch my chin, hands, and hips. I'm hesitating to take steps because we knew each other as friends and i dont want to disappoint her on that. How to confirm if they are hints and she has feelings for me?
