In a survey of 1,000 married women, the Daily Mail found that half of them have a “fall-back” partner in case their marriage doesn’t work out.

Backups included ex-boyfriends, ex-husbands, colleagues and friends from the gym. Ten percent said the backup already confessed their love and twenty percent said the backup would drop everything if required. The most common backup was a man the wife had known for around seven years.

No word on whether married men should have a backup wife.
