<human>: Can you condense the text into a few key points?

So for some background, I've known this girl for around three years, and have pretty much had feelings for her the entire time, but kinda forced them down and convinced myself they werent there for a majority of it, because she was dating a good friend of mine until around six months ago. I've had a couple of girlfriends during that time. My ex and I broke up around two months ago, and after a while it kind of started to come back up. 

So, fast forward to around a week ago, she and I got kinda drunk and wound up having sex a few times. Afterwards (while sober), there was cuddling and talk about having feelings towards each other. Two days later, I went over in the morning, and we slept together for a few hours and had sex again, after which there was more laying and you get the idea. 

I was very happy, and she seemed to be too. We ate breakfast, and I took her to work. She kissed me goodbye and we were texting back and forth as we usually do, and from time to time there would be talk in a relatively romantic/flirtatious manner.

After around 12 hours of sudden radio silence, she texts me saying she only wants to be friends and wants this to go no further. I don't get it though, because not 24 hours before that, she seemed to be very enthusiastic about it, and it wasn't just sexual considering the rest of our conversations. 

I told her that it was fine, but i'm actually really busted up about it. It was easier to deal with before, but now i've had a pretty thorough taste of how fucking happy that made me, which made it a lot harder. I don't really know what to do, what happened, or how to deal with it. Anyone got some advice??
<bot>: have been in love with best friend for a while. We had sex, admitted mutual feelings, and suddenly she dropped off and just wants to be friends, but I still want to be with her.
