Search Results: complicated relationship status

So I met this Korean girl today for a casual meeting at the college, not a date or anything. The premise was to help her with her English, though we spent most of the time talking and the only English I "taught" was when she couldn't understand a word I said or something like that. Anyway, I noticed that she's very open. She has open body language, leans forward the whole time, no arm crossing or other closed off signs. She often touched her hair, running her fingers through it and stuff (she didn't do that the whole twirl her hair around her finger thing though). At one point, she asked if I was thirsty and then bought me a coffee at the nearby cafe. She said it was for me spending time with her.

We touched a few times accidentally and she never pulled away even when our hands were against each other for like 10 seconds as I showed her something. When we left, I asked if she had fun and she said "Yes, thanks to you! I have lots of fun around you!" When we parted, I shook her hand and after a few seconds (she wouldn't let go), she initiated a hug with me.

Here's the problem: she has a boyfriend way back in Korea. She's never mentioned him to me, though to be fair I haven't asked. I only know because of her "in a relationship with (Korean guy)" status on Facebook. Regardless, I have absolutely no clue where I stand. I'm meeting her for lunch next week and seeing where things go from there. Does she like me? What should I do?
