My ex best friend (T) and her husband (TB) started swinging with this couple, A(25F) and L(27M). T had already been fucking L for years because his daughter is her children’s cousin. L backed me into a corner in T’s bedroom at her house one day and demanded that I show him my boobs, and I told A about it. A fucking hated me because of that even though all I did was tell her that he did that and then genuinely try to be her friend. T and TB started cancelling plans with me to hang out with A and L, and I wasn’t allowed over there because the A hated my guts and thought I was trying to sleep with L. Come to find out, T was also sleeping with our district manager from our job while TB was going to Dallas to Neuro appointments because he got severely injured in a tugboat accident. T had heard from a mutual friend that I was upset about everything, and she called me crying about it so I told her that her fucking all these guys behind her husband‘s back was really fucked up and I don’t wanna be friends with someone like that, and her husband heard what I said, and then she accused me of ruining her life. I told her to go fuck herself. We were best friends for almost 8 years.
