Me a (19F) tried to make my friend, let's call him Edrick (18M) stop being bestfriends with the girl, let's call her Sylvia (18F) i don't like. For background i don't like Sylvia because she has bpd. I know that it sounds horrible but let me explain. Because she constantly insults him but at the same time she is way too clingy. I mean, Edrick insults her too but its different, he obviously means it as a joke, but i have a feeling she is serious about it. (besides she is a lesbian but she kisses him and says that she loves him and can't live without him. i know that they have known each other for like 11 years but it gives me an ick) So, I have a friend, let' call him Joseph (22M) I've known him for like 3 years, i consider him my bestfriend so i told him about Sylvia, and he also thinks that she is weird. I told him that i'm worried about her hurting Edrick, even tho i don't have any proof that she might do it, i just have the feeling about it if yk what i mean. Edirck told me that he's relationship with Sylvia is mutual, in the sense that they both insult each other for fun, but i refuse to believe him. So, i decided to make a plan that would split them out. I told Joseph to talk shit about Sylvia around Edrick in hopes of him turning his back on her. Sadly, my plan backfired, he realized about it and he doesn't want to be friends with me anymore. I just wanted what's best for him and help him, but i guess i am the bad guy now. He now hates me and i don't understand that, i don't think i've done anything wrong.
