<human>: Condense the text into a few key points

I hope this is the right subreddit to post this, but here goes:

I've been talking and hanging out with this girl quite a lot recently. I have fairly reliable information through her friends that she is interested and I'm sure she knows that I'm interested as well.

We hang out at least once a week, and text almost everyday. All signs are pointing to yes, but I've had a very hard time getting through to her physically. There is no signs while I'm with her that she wants to be touched. I've tried putting my arm around her and the like but the way she reacts to it leaves me very uncertain. We have been hanging out for at least a month now but no progress at all seems to be made. I'm really at a loss at what to do. Apparently she has been like this with every guy, and has actually not had a relationship yet so I don't think it's anything I'm doing wrong in particular.

If anyone has some advice on what I can do to get through to her, or to avoid doing that may scare her away I would be so happy. I'm really at a loss because my own relationship experience is very minimal, and the relationship experience I do have didn't involve me making any of the first moves. I really want this to work out but I feel like I'm banging my head against a wall at the moment.
