<human>: Can you summarize the given text in a few sentences?

So, I have a female friend that I have know for a couple of years. We were never really close until just a few months ago. She invited me to hang out at a bar and we had a good time. We talked more than we ever had before. Since then we have been talking more and seeing each other more often, but usually in group situations. A couple times when we have gone out drinking, she starts getting a little touchy. Putting a hand on my back and leaning in to say something, or putting a hand on my arm, or hugging. She also talks a lot about guys she dates, but mentions they are all people she just wants to see casually, no real connections. 

I am a massive over-thinker with little dating experience, so I really can't tell if these are signals or of we really are just becoming closer friends. I've heard women talk about how they think they are sending these obvious signals, but the guys are just oblivious. Could use some help or opinions.
<bot>: Massive over-thinker not sure about see "signals" from a friend. Does she like me? Should I try pursuing anything?
