cohabitation

The obligation of cohabitation of spouses is the basis of marital rights.

夫妻间的同居义务是夫妻其他权利与义务的基础。

Or maybe it's about spending more time together if you're not at the cohabitation stage yet.

或者如果你们还没有到同居的阶段，或许只是花时间在一起的问题。

More second marriages fail than first marriages. With the increasing acceptance of cohabitation, why remarry? Why risk that nightmare all over again?

更多的第二次婚姻比第一次更差。伴随更多同居被接受，为什么要再婚？为什么要再冒险那个噩梦？
