<human>: So I'm a junior in highschool and never had a relationship before, but beginning of sophmore year I met her  and we had been friends before for maybe a year before but we got a lot closer sophmore year and found out we had a lot in common and she quickly became my closest friend. Texting/Snapchatting constantly (though I would say she was quicker to respond than me always, and always sent the last msg, etc) but overall its's great, yay.

Fast Foward to that summer, we're both in orchestra and we're both really close at this point, and orchestra goes to Europe on a music exchange program for 2 weeks. Probably one of the best 2 weeks of my life, we spent basically the whole time together and at this point I'm starting to realize I like her. 

Fast Forward again to homecoming in October Junior year. Great night, we both have a blast, etc. We're holding hands and stuff yay..

Alright here's the problem - around March of this year she stops texting me, avoids conversation and eye contact and it gets really awkward. A month later in april, I'm super worried so I text her and she tells me during that time in March she decided to focus on academics and sports more, that she liked me more as her best friend for a time, but her feelings "have changed". 

Now she's barely talking to me, and I don't know what to do now that I still like her and I know she doesn't. Overall really confused as to how/why she would just change her mind like that.

Can you provide a brief overview of the text?
<bot>: I like my bestfriend who used to like me but all of a sudden decided she didn't, and don't know what to do or say.
