For backstory, Ive known these girls since high school, I talk to Bitch1 frequently even though we dont live in the same state anymore.
So Bitch1 posts a snap of her and bitch2, bitch1 looks so great, but her friend looked straight up fat (even though she has a nice curvy body in person and all her other photos.) I sent a PM saying
"your mean for posting this, it's so unflattering😂"
trying to make light of it. They BOTH came back at me in snap videos calling me out on the most random stuff "oh but your high school boyfriend cheated on you? Ok." And saying they want to physically fight me! The 3 of us are in our mid 20s, I honestly thought she could take the criticism.

TL;DR I told who I thought was a good friend, that their photo was unflattering and they dragged me.
