At the beginning of this year I met an HB8 at uni and she was applying for some internships in a sector I'm pretty knowledgeable about. We talked quite a lot about this but also about more personal issues but I never signalled any further interests, even though I had the impression she liked me and we could talk for ours about all sorts of things.
She got the internship and wrote me a nice thank-you message, saying talking to me helped her a lot. Later I messaged her on facebook but she didn't reply (maybe busy bec of exams), but two months ago she started commenting my fb statuses and liking some of my pics. At the moment she is in China (no email and facebook) but she'll be back soon.
What's the best way of reestablishing contact with her? And how can I get things to a different level?
Thanks for your help, guys!

I would talk to her maybe 5 minutes on facebook, asking how was china, and then I would leave and tell her " when you comeback I will call you to hang out and talk about china or the internship" Then Voilaaa
