Is AUTHOR wrong in the post ? POST : I am very confused and just want some genuine feedback , Thanks!

Context: My friend's GF and I were really close friends up until this point. For this story i'll call my friend luke and his GF chell. (Nowhere near their real names) Also I'm Bisexual , that will be important later on.

So for this to make sense I have to start at the beginning. Basically , Me and chell were friends since  kindergarden and up until now we never had any arguments or troubles between us. However last year I asked her "Do you Wanna Be my Girlfriend?" Which  she  Replied  "No , Sorry." To be honest , I was heartbroken , but I brushed it off and pretended like it never happened. People around us and in our friend group teased us about it and we still joke about it to this day but we carried on being friends. At the end of the year had asked her , "Do you want to be my Girlfriend?" and she said "No.". At this point I was mad , not only had I overheard her talking to her friends about how she thought that I was "Funny" ,  but she had also flirted with me  before. Not to mention the fact that we were such close friends. Shortly after this , she sorta fazed out of my friend group. We still sat near each other but didn't talk as much , and finally the end of the year came. Fast forward to start of this year , she has a "Boyfriend". Which was fake , and most likely just made up to ensure that I didn't ask her if she wanted to be my girlfriend again. I felt kind of insulted , especially that after us knowing each other for years , she wouldn't even give me another chance. "That's fine"
I thought to myself , I've seen examples of people Being "Just Friends" and still having a very nice friendship so I wasn't too worried. Around this time I had also "Came out" to my friend (Luke) telling him that I was Bisexual. After her attempt at having a fake boyfriend ,(Which everyone found out) , I decided ,     "Welp , if I can't get a girl might as well find a guy." While I was trying to figure out ways to Ask my friend out, The universe gives me a huge middle finger , Chell and Luke become a couple. Not only was I mad because they Are/Were two of the only people in my school that I was attracted to , but they had NOTHING in common! I Won't go into the details but trust me when I say NOTHING in common. I Honestly hate her , no doubt about it.
