Ah, me and T. That was an interesting friendship, to say the least, also probably the most toxic relationship I've had, of any sort (Romantic or not)
She was the girl I met in maths class in.... 9th grade? I think it was 9th. We became friends quickly, mostly just talking in class at first but before long spent every lunch together etc, and we slowly built a group of friends, which eventually became fairly large.
By the start of 10th grade she was my best friend, and I was in love with her even though she wasn't interested. She knew how I felt, and she took it as an opportunity to screw with me whenever she could, like whenever she was dating someone she would have huge PDAs deliberately infront of me and the like.
But we stayed friends, for a while. Mid 10th grade, I was having to be at school really early because my mom was working and couldn't drop me any later. T lived near the school, so would come early on the days that I had to and we would chill in the usual spot. On those cold as shit mornings we would talk about all sorts of things, very private things...atleast, she would encourage me to say anything and everything despite how reserved and private she still was. This was a mistake on my part. More on that later.
A few times when she was in between boyfriends and I was bored or pissed off at her for something (like her not inviting me to a party, ignoring me for days/a week at a time with no explanation), I would try to get a reaction out of her by telling her that I loved her. She never took this well, and given that we were having frequent fights (she was very arrogant, so challenging anything she said usually led to one) it felt good to upset her sometimes, because I usually came off second best.
So basically, two way emotional terrorism.
Soon after one of those "I love you" incidents, she started seeing someone, lets just call him M. M was...sort of a friend. Everyone knew him, everyone like him, but I never expected him to end up with T. Anyway, because I liked M, I stopped screwing with T that much for his sake and drifted off to another part of the ever increasing friend group (which itself had, like, 3 different factions to it. It was weird).
Eventually, T posted in facebook that she and M had broken up. This was toward the middle to late 11th grade. She was acting like it was the worst thing that ever happened and that she would never recover, so I posted that highschool romances rarely last and that there will always be more.
This was somehow the post that tore apart a friendship of multiple years. Posting that not all romances last. She thought that I was taunting her, trying to mess with her, trying to cash in on her grief to bang her (I wasn't, I had moved my interests to someone else at this point).
So what did she do? She posted, on facebook, all of the secrets that I had told her on those cold morning where we were both at school early. Every thought I had ever had about my sexuality (and a minor crush I had had on one of our other mutual male friends, briefly), every thing that has ever upset me, all the other girls I had been interested in but never told...all of it. on facebook. in public.
That was... shit. Like 8 years ago now? Havent spoke in 7 years (last time we ever spoke was at the graduation dance, and that was only like two words. We insulted eachother).
Highschool was crazy.
