<human>: So i posted here a while ago about this girl:

So there is this girl (she has been one of my bestfriends for a while), and over the winter break, we were talking and everything was fine. But then a few days before NYE, she stopped texting me back, and I'm thinking it's normal, that she might of had something to do. But as the days go by, I don't try to talk to her, while she still posts on facebook, etc. Then at school today, I go, "Hi, ____" to which she replies, "Wow, awkwardddd..." And I'm left there thinking what I might have done, or whether she just feels awkward around me because of something else. WHAT"S GOING ON WITH HER (or me)?

A few days after I posted she tells me that she stopped talking to me because of her friend that has a crush on me, and that it would be wrong of her to talk to me while her friend still has her silly little crush on me. The next week, she (all of a sudden) comes behind me and hugs me, telling me that we can be  friends again, and everything seems great (for the next 6 hours or so). That night, I try to text her, like we used to, and I ask her what made her change her mind. She said she didn't know, and she was just "going with the flow". I asked her what her friend thinks, since she was the reason she was so concerned in the first place. She doesn't respond, and now everything is awkward between us again. We pass each other in the hall, and we don't even look at each other. I've run through my apology/reason for mending our friendship a million times in my head, but I can't seem to approach her in person, much less press send on my phone. 

I DON'T KNOW WHAT TO DO REDDIT. WHAT'S WRONG WITH ME. I JUST WANT MY BESTFRIEND BACK.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: things are awkward between me and a girl, then it's ok, now it's awkward. what do i do?
