Sister Ex

Your ex's ex with whom you have become friends. The friendship starts out as a trauma bond, swapping stories and comparing notes on the dude's lies, cheating, and manipulative behavior, and evolves into a genuine sisterhood.

I'm getting together with my Sister Ex on his birthday to wish him a year of pain and misery.

My sister ex confirmed he was cheating on her with me when we met.
