When An Ex Cancels Out Another Ex

(Five years ago, the ex-girlfriend of a former roommate married my ex-boyfriend. That was one year after I had broken up with him. I didn’t attend their wedding, but we are friends. I get invited to her birthday at their bungalow in the woods. This conversation happens while passing each other in a doorway, with no other people in earshot:)

Me: “Your house is lovely! It must be a breeze to live out here.”

Her: “It is! Oh, why don’t you come live here? We could be [Ex-boyfriend]’s wives together!’

Me: *awkward blank stare*
