I think my best friend used to have a crush on me

This is a long time ago story but I am still curious if she actually used to like me or not. So let me tell you how it starts.

At first, when i met her, she is the kind to be funny around people but i have never seen her smile or laugh. It is like she makes joke while doing a straight face. I starts to get attached to her because she is the one that been friends with me after everyone left me.

But then a few months after I start being friends with her, middle school is about to end and we will start a high school life. So our friend group in the middle school just part ways. When high school starts, I was really excited to see her on the same school as me. But she keeps ignoring me and acting distant. But I didn't give up and force myself to her (i know i shouldn't do that but yeah its an old story) . She starts to get close to me. The first time i've ever see her smile is when i made a joke about something and she laughs. That is the first time for me.

Those times, I just treated her just like my best friend until one day, I was doing a presentation infront of the class, it was very loud and energetic until I saw her looking at me as if she was admiring me. I never saw that look on her face before that I freaked out. I kept calm and thinks it was normal and its just a friendly stare.

Until one day we were having a class that teaches us about homosexual/bi or whatever. Then the teacher for no reason decided to makes an example of me having a crush on her(the worst that could happen) , i tried to keep my composure but she kept grinning and smiling nonstop. I don't know why she did that.

She literally knows about my life, family, etc but one day she stills decides to make fun of my dead cat in the group chat. I tried to stand up for my cat but my other friends keep supporting her which makes it a 2vs1. I started hated her since.

One day we had a really bad fight and she decides to stop being friends with each other. Yeah, she decides.

But then when we are at school she still tried to talk to me and tried to fix the relationship. I was pissed because she is the one that decides to end the friendship so I act cold towards her. She becomes really pissed and immediately has a bad mood the whole day that she refuses to talk to anyone even her other friend.

Its been a week and she gradually starts to wind down when I started talking to her again. Like when she is hanging out with others and I joined with intentions of spending time with the other. No matter what I say she kept laughing even though its not really that funny.

We didn't really become close like before anymore but we still talks, until one day we have to gather in the hall, she said she wants to sit behind me so I just let her. Until when I turned around to look at somethings else,but caught her admiring me again. I starts to avoid her again and she is back to her bad mood.

But now currently, she is not like that anymore. She became matured i think.

There is more but I'm too tired to type, so to the people who read this far, what are you guys opinion about her? How does she feel about me?
