I already had 3 dates with a girl I met about a month ago. We met at a party, after that we were texting for about 2 weeks and then she invited me to her b-day party when we hooked up, then a few days later we had our first date. It's all fun, but the problem is she is passive so far. I mean, she won't text me if I don't do it first, she doesn't call me, although she immediately agrees to go out if I invite her (if she is free of course). We hug, kiss, hold hands and stuff like that, but again, she won't kiss me unless I go for a kiss (except for a couple of times when she kissed me on the cheek). It's like, she doesn't back up, yet at the same time she won't take initiative for anything...
My question is: is she still a little afraid to open herself, because it's too early, or is she playing some kind of games to me? I would take any advices, guys
P.S. I'm new to PUA, so I might sound a little noobish lol
