<human>: I need some help with girls  
And honestly, I had no idea who to go to  
So i am just going to explain my situation now

So there is this girl I like a LOT. Like I am totally head over heals for her. I met her on a school trip, and I totally thought we hit it off. I thought I was totally "in" in the beginning, but about halfway through the trip, she started hitting on this other guy hard, and on the last day she ended up doing some sexual things with him. (Ouch town my ego). When we got back, we started hanging out a lot (texting, snapchatting, watching movies, playing video games, a lot of things). Well basically, I told her how I felt and i'm 90% sure that I got rejected. (She claims she is emotionally confused right now).
Now this girl is definite best friend material, and I don't want to ... not be friends with her
because she honestly likes everything I like, but its so hard to see past the fact that I have hopelessly fell for her.
What would you recommend I do? I have no idea what the hell I should do. Do I just stay as a good friend? Or do I kinda just ease myself out of her life to save myself the pain/drama?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Got reject (I think) by a girl I really like, and want to stay friends with, but have no idea how to handle the situation now.
