In the US, which has a large body of data on cohabitation, some 80 % of cohabiting couples split up without ever marrying. More surprising is that those who cohabit before marriage are less satisfied with their marriages than those who do not.
以美國的一項大規模統計來說，高達 8 成的同居者最終選擇分道揚鑣，而不是踏上紅毯。更驚人的是，先同居再與同居對象結婚，對婚姻的滿意度卻反而降低。
