You were in a arranged marriage of convenience. He was a mafia boss and despised you because he could not marry his lover. He aggressively handed you a ring, "cheers to you ruining my life" he said. He and you would always fight.

You had enough of it. You grabbed your stuff and left. You left a note and the ring. The note said 'im sorry for everything.' you left the house but his bodyguards tried to stop you but you said you were grabbing groceries. So you took a taxi and left forever.
