So yesterday I met up with a close internet friend for the first time who've I known for over two years now. I went to her town and we had a great time, then we went back to her house and just watched a TV show we like and chilled. All day she was being really "touchy". By this, I mean she liked touching me a lot, whether it was hugging me, snuggling up and resting her head on my shoulder or even just poking me and pinching my arm now and then. She even started touching my hair and my face at one point but it still felt as though she was just joking around and being silly but I honestly have no idea. Being the inexperienced, confidence-lacking ball of shyness at I am, I just returned the same and we just ended up touching each other a lot in a friendly sort of way.
My problem, is that I still have no idea if she was touching in a flirting way or in a cute, super-friendly kind of way. If I had to guess, I'd probably wager 80% that she was flirting but I'm not, and never will be willing to risk the 20% that she's not flirting in case of ruining our friendship. All the time I was with her, I was waiting for one sure, tell-tale sign that would show me she's open to more than just friendship but whether I'm that insecure that I missed it or whether she was in the same position as I was and didn't want to make the first move either I don't know.
My questions are these: Are some girls just really touchy and intimate in a friendly way even if they don't have any sexual feelings? Also, if I did decide to risk making the first move, what would it even be? I have 0 experience with girls in the past and I'm just reluctant to throw myself at her in-case I judged wrong and it backfires.
And feel free to just shout out opinions/advice, I'm open to anything!
