I Have Lgbt Relationships

Okay here is the thing.I like so much a girl from my University.As a person she seems very girly but she is not very sociable and she is shy and she doesn't talk much.She only have a friend that she is hanging out with (In University) The thing is I can't get ANY information about her what she likes what kind of a person she is etc because she doesn't have any social media (like you don't get to know a person through Instagram but you can see what she likes,where she hangs out,If she is in a relationship etc) We talked once or twice in Uni (but only for things like our classes ) and we talked through Viber because I started a conversation and again we send notes to each other etc but she was very sweet and kind but she didn't talked much either.The thing is I don't know how to approach her. I know If she cared she would make a move but she prob doesn't have Idea that I like her. Also I want her SO MUCH to know that I like her because If she knew something could happen between us because she will think of me this way,or she would just reject me but she won't be annoyed and she would be nice,In the other hand what If she would be annoyed? What If I hurt her feelings and she feels awkward around me all the time? I don't want any of this to happen.Iam a person who always give advice like "If you like someone tell them otherwise you would never know what could happen also it's beautiful when you love someone to tell them" BUT If I was a boy I would.Or If I knew she likes girls I would.Or If I knew her better I would give a try even If she rejected me she wouldn't feel bad.But What I do now????
