Been talking with a girl who has been giving me mixed signals?

I have a girl I've been friends with since high school to make a long story short we fell out of touch because of circumstances beyond our control. Recently we've been talking again and found that we had a lot more in common then we both thought. We went out alone one night and talked to each other for hours she told me she was almost married and broke it off with her fiancé after he turned out to be stealing from her along with other things. Throughout the night things got intimate and we ended up kissing and she held my hand and arm the entire way home. I assumed we were in a relationship at that point. Everything between us really kind of ( and I know this is cliche) clicked. Few days later she began to become kind of distant and I ask her about it and she claimed she didn't think I had the " whole gf thing on my mind" and that she would feel comfortable just staying friends for the moment and get to know each other more. Yet now when we do talk (and that's rare) its as if I'm talking to a stranger. Almost a week ago we met up again and she took a friend with her. she was warm and friendly just like before and we had a great day. However, I haven't really heard from her since and her friend has been blowing up my phone. Im starting to wonder if perusing her is worth it. Am I being toyed with or is she just hesitant to open up to me? I've been confused and hurt by a lot of this and I don't know what to do anymore I typically try to stay away from relationships anyway is this a good idea or should I quit?
