18/m my best friend/crush19/f Get out of friendzone

Well I have loved this girl since I met her, we are really close and tell each other everything and always have each other's back. I would do anything for this girl. A couple of days ago I told her everything about how I feel about her. She told me were just friends and that's all we'll ever be. I asked her if I am ugly or should lose some weight, is it my personality? She said no your good looking and I love your personality. But we are just going to be friends.

Reddit is there anything I can do? I even asked her to go to NYC with me and watch the ball drop together. Normally we do things like this but just as friends, and now she won't even do that as a friend...

When I text her now or call her she ignores it or gives me a one word answer. What can I do and what should I do? I've known her forever, slept over her house countless times, i have become preety much apart of her family, her parents want me to date her they love me so does her family. But she isn't having it...

Edit : it seems like she goes for the asshole guys who dick her over, I just don't get it. I even supported her and was nice to her asshole boyfriend of one year. But they are no longer together and despise one another, and here I am still supporting her, even when she is now literally throwing herself at any asshole guy she meets. When she meets a new guy she texts them non-stop and pretty much thinks their the shit.

Edit 2 : I've been best friends with her for 4-5 years, can't remember.
