What ended your relationship with your best friend?

My tenth percentage ended my 8 years friendship

But I politely rejected me and stayed as a friend

(I was the last person to know about their relationship that to at the end of 12th)

Belmont Stakes: Hill Road faces challenges beyond tough field - Horse Racing Nation

When I told my friend about this she just ignored me by saying I am soo jealous of her

Everything was nice until our 10 result and I got more than her so she started to distance herself from me and d got some new friends

X spoke me too friendly and the same day I got to know that Sara and X are in relationship for almost 1 year and x trying to get me all this time

My parents force me (15yo atheist) to go to church, and there’s this thing called Small Sundays where we discuss the Bible in groups, there are questions asked about the Bible. What am I supposed to do when they ask?

Things became worse when my other classmate (let's call him x) came between us

…… Never hate urself for some unwanted people and trust them with ur secret 💕

Fast-forward to 8 months

What is the happy reality of our generation?

And she just replaced me with a new friend and I spent all my last school days crying and hating my own character 😞

Well me and my friend let's call her Sara (name changed) were the only girls in the whole class of 10 students so obviously we both are close with each other but because of my little cold character and straight forward talks we always had some small fights

So first X became to close with me and even called me with nicknames and approached me saying he had a huge crush on me

What have I done wrong? How can I start over?
