Normal for my sister to follow my ex best friend on instagram?
She knows I stopped being friends with her because she was a psychopath. She slept with my boyfriend at the time, stole money from me, made up lies etc and my sister knew all of this but found out they're friends now... They weren't even friends in high school, my sister was 3 grades below me because she's younger so she never hung out with my best friend at the time. She knew everything, knew how much she hurt me and now she's friends with her 🤦♀️ and they're basically best friends now because when I asked she said oh we've started hanging out for the past few weeks but I followed her on Instagram since you guys ended your friendship..why?? Why would she? She's going to be one of the bridesmaids at the wedding what.. what even
