How to get close to her? Really need help here :/?

[Nick]

I am in international school (in Holland) and this girl in my class likes me, but the thing is that shes 19 years (from vietnam) old and im 15. Shes really pretty and she looks like shes 16-17 years old and we dont really have much in common and we dont really know each other well. She never uses facebook so shes never online to chat with her, she doesnt have skype so i cabt really talk to her somewhere other than school. We get along great and shes fun person to talk with and we really enjoy it but sometimes i dobt really know what to say or how to talk to her, Im not that skilled w
ith girls... I never get nervous around her abd feel free to talk about anything but still im afraid sonetimes cus of age and cus i never had a gf before. So can anyone help me? I dont really know what to do or how to get to know her better so if you have any tips or anything it will be helpful.

Thank you for answer and sorry for grammar.

OMG how about cellphones?!
Or just simply tell her to get a skype :/
Anw I'm a Viet girl myself, I think Vietnamese girls are quite prudish and respectful lol
You dont need to worry that much tho, age doesnt matter at all, not mention that Asians age really well
Good luck man!
