Some persons may have a sense that the faith tradition in which they were raised discourages cohabitation (e.g. considering it to be morally problematic), but: they're not sure why that's the case, they want to be with their SO, they wonder what's the best way to prepare for life together as a married couple (per the comment to which I replied originally). So, on the one hand, I encourage such persons to learn more about why their religion (and/or the religion of their parents) teaches what it teaches[+]. And on the other, to recognize that there are good ways to prepare for life together that don't involve cohabitation.
