Replying to Girl help

Long story short I've liked this girl for a while and have been really close friends with her, and she'll always invite me to cum hang with her. never though I was friend-zoned because she never talks about deep gay girly shit to me, and because she has 2 guys that are in the deep friend zone. I get mixed feelings from her tho, one day she'll always cling to me, and others she'll give me "da fuq u staring at bitch" faces. Wat do NS, also last week she asked me how to turn down this guy and how to do it (this guy is not bad looking)
