When a woman let's me touch her shoulder, and or rub her back?

I've known this woman for a few months now that I've started to really like. I'm more of a touchy person when I'm interested in someone, so I'll do things like gentle back rubs, hand on her shoulder, hold her hand for a few seconds, stuff like that, (this entirely depends on the situation, and on how the interaction goes.) Whenever I do these things, she doesn't pull away, and isn't verbally disgusted by me. Does that mean I have a chance, or is she just simply comfortable with me?
