For context, my ex bsf (16f) and I (15f) met via school friends and have known each other for 1 year prior to our friendship. We only became close at the start of high school and we are now in year 11 and no longer friends. Lots of my friends didn’t like her and told me to stop being friends with her but I defended her and didn’t listen. After being her bsf for 2 years i started to have doubts. She lived close to me and we both live far from school and take the bus together, so we hang out a lot. Everytime we hung out she would pick a fight about something especially really small stuff. We are both really different by what our family is like and have polar opposite tastes and opinions. She wpuld make me start to second guess myself and would never admit when she was wrong, but i felt bad for thinking that bc i didnt know if it was intentional and i tried to brush it off. Yea we had lots of fun together but it always ended in her getting mad or blaming me, and we would sit in silence before pretending it didnt happen. She and i were super close so she new everything about me, but she didnt tell me a lot about her, though she told others. One day at school, we both got into throuble bc of something she did, and i admittedly did too bc i though what she did was wrong and deserved some sort of repercussion. We both ended up in trouble and got detention. My dad talked to me about how much trouble i was in and whenever someone yells at me or confronts me, i start to cry. So i told my at the time bsf about this and that i was crying, hoping she would comfort me, she proceeded to call me a liar bc she was crying yesterday and told me about it and thought i was copying her for attention. She said that it “wasn’t her problem that i got into trouble”. I never loose my temper at people out loud, just in my head but i told her (over text, i could never do this irl) that i don’t want to be friends anymore. She thought i was joking but then realised i wasn’t and said “okay well bye then” i was super sad bc i missed our friendship but i also remembered all of our fights. A few weeks later when school started again (i broke up at the end of the school year) she asked if i wanted to be friends again. I don’t know what to do maybe i was wrong and completely overreacted and i owe her an apology. But i feel like if i go back our friendship wont be the same. And now i am always everyone’s second choice. Reddit please tell me AITAH??
