Honestly I feel first you should ask her that question and think over her reply! In the other side i feel she isn't a trustable girl!
How can I ask her out because she never talks to me. She tells everything to her male friends whatever I say to her?
Doesn't sound like much of a future there to me. Might be best to set your sights on someone else or see if she comes to you. If it was me, I would be looking for a different girl that talks to you and cares about you as this one doesn't seem to.
