I love her, but it is complicated. Please help me what should I do?

She sounds like she likes you but is playing hard to get... if i were you i would take her to see that film and open up your feelings towards her, let her know how special she is to you. It sounds like she and her best mate are waiting for the moment that you and her get together to happen but they are waiting for you to make the move.... her best mate is trying to give you a hint there ;)
