I'm not sure about this but I was in a all girl group in high school.
It was my ex gf, her sister, two other girls, and myself.
It was a good time for a while, but also super stressful since I was a turbo autist in disguise. I was walking on egg shells for a whole 3 years trying not to do or say anything to get me kicked out of the group.
Eventually though the dam started to leak and my true personality began to leak out.
My gf's sister was the first to resent me, and it was a slow passive aggressive downward spiral until the break up.
Haven't talked to any of them since.
