英國每日郵報的一篇報道說,在戀愛中,過半女性都有"備胎".

A report by the Daily Mail says half of women have a fall-back partner on standby who has always fancied them, in case their current relationship turns sour.

A substantial percentage have kept another man in mind in case they end up single.

And married women are more likely have a Plan B in the background than those who are just in a relationship.

It also emerged the back-up is likely to be an old friend who has always had feelings for the woman in question. But other candidates are an ex-boyfriend or ex-husband, a colleague - or someone who they have met at the gym.
