Input: backstory, my ex (we'll call bitch, petty but i don't care), we hooked up for about 2 months before she dumps me and returns to her ex, which means i was played as a rebound. I'm a really nice person as a whole, and it's hard for people to really piss me off because i never take anyone's threats seriously but if you get on my nerves i become the most petty nightmare, and it never ends because you're officially put on the "shit list" for me.

for the year after the breakup i didn't talk to her, talk about her, do anything that has to do with anything remotely close to her... until a few weeks ago where she started talking about me behind my back.

i tried messaging her, i was blocked... i messaged her best friend, she tells me that she's been spreading lies everywhere about the breakup and me lying about a few things... and thus, i got royally pissed.

first, i established a close friendship with her best friend a her only ticked for a visa to a different country, and ended that friendship as her friend now hates her guts too.

went off to talk to another friend that she just made up with after causing her trouble too, now she broke that friendship too.

i made a half-hour long video explaining everything including screenshots of texts and voice notes and call recordings and sent it to everyone that she knows and know her.

then i decided to fuck with her boyfriend's brain until he grew paranoid of her.

her being an introvert means that she can't make friendships here, and me destroying whatever what's left of her friendships made me feel like an asshole, but a justified one.

so, i leave the question to you, fellow redditors, am i an asshole in this situation?

killing all of my ex's friendships
