N'anniversary
If you were married for less time than you were broken up, then the day you got split still belongs to the universe, and it’s not your anniversary, it’s just your sad face day.
My ex said it was our 5th anniversary, but I was single for 7 years. She’s delusional.
He posted a picture of our wedding day and called it our 10th anniversary. I was divorced for 12 years.
She sent me a card saying 'Happy 3rd anniversary,' but I had been separated for 5 years. She’s got issues.
