I met this girl a few years back, we instantly clicked and became best friends, everything went so well until my father became sick last year in september.
She had her own issues going on so I didn’t blame her for that, then she started dating a guy she only knows because of me, from there on the abandonment began.
My father who was also my best friend forever passed away in february 2019, She was one of the first people I texted when it happened and she was the last one to reply to me, again I was upset but I didn’t fault her.
she started messaging me less and less, from talking daily, we went to talking every few days.
Everytime I brought it up, it was brushed off, I was told I’m being selfish for wanting to be part of her life and have her be part of mine.
I was told that I want her live to revolve around me which really wasn’t true at all, then came all the excuses about how her mental wellbeing is so horrible that she doesn’t even have a minute to herself, all the while posting conversations with everyone but me across social media, being on facetime to her boyfriend daily but still leaving me in delivered for days if not weeks.
She has not spoken to me since early November  despite me reaching out every now and again.
I’m not sure whether it was shortly before or shortly after new years I had sent her a message on Snapchat asking where I went wrong causing her to not want to speak to me anymore, she saved the messages and left me on opened (read). 
I have been using her netflix account for a year  because she offered me to use it.
Earlier today, as I was watching something, she changed her password, it sent me on a spiral and I feel so broken.
At that point I deemed the friendship to be over.
My heart hurts and I just feel like absolute shit, wondering if i could have prevented this.
