"I've ... apologized accordingly" Have you, though, really?
It can't be that your feelings and history aren't an excuse, can it?
"I just want to exist
positively in my community of mentally ill teenagers where everyone gets exposed as manipulating everyone else twice a week and we all hash it out in our regular attack therapy
dogpile PUPPYPILE sessions!"
"I would've apologized for this fucked up shit I did to you when you confronted me about it if only you had been
NICER to
ME"
Man, I'm pretty sure everyone has considered that he was victimizing her. Hell, weren't people speculating about him grooming her back when they were still together and she was still defending him? No, people have considered this, and after these considerations, come to the conclusion that being victimized doesn't excuse victimizing and perpetuating the victimization of others.
PFFFFHAHAH aaaahh fuck off. Gain some self-awareness.
