Help with a Girl Problem, I really need advice..?

Ok so I am in my second semester of college. I just transferred and in one of my classes I have around 15-20 people in it. So after the 2nd class, I go home and find I have been requested as someones friend on facebook. Its this girl that stared at me coming into the class, and I guess she got my name off the attendance sheet and friended me. I mean I never sat next to her or even talked to her once, but she still found out my name and friended me. She sent me some messages on facebook and said to talk in class and whatever. So the past 2 classes, I have been sitting next to her and we have been talking after class until we reach our next classes. The thing is, it says she has a boyfriend on facebook at another school in the country and were together before college and now still are, yet what the deal with me then? And her main facebook picture is of her and her boyfriend, and she has a bunch of pics with her boyfriend Its making zero sense, i want to talk to her more after class now and see a movie or something, but I have no clue if I should or not because of the boyfriend fiasco. Then she asked me for my number 2 days ago afer class and said she will call me or text me to do something soon. Then i texted her happy birthday yesterday when it was her birthday and she didnt reply. Whats going onnHelp with a Girl Problem, I really need advice..?

The best way to find out is to ask her.
Hmmm that's really weird. I'd watch out for her.
She's not your girl friend. A classmate. If your not willing to be the in between guy then don't be. Don't make it more unless she makes it more. If you want more then say so. Get an understanding. You know she has a boyfriend. If your feelings get hurt you have only yourself to blame. Knowing her for such a short time means she owes you what? You said happy birthday! A bag of cookies is in the mail. Wait for it. Are you looking for a wife? Change your pool. Have fun! Your young. Good luck
