Should I recommend that the couple proceed with a trial marriage?

My close friends, Alex and Meredith, have been dating for nearly two years.

They have talked about marriage for several months but are wondering if they should test their relationship and get used to living together first. They came to me for advice.

Using research in Helgeson 2017 to support my answer, what should I tell Alex and Meredith about cohabitation?

Based on the available research, Should I recommend that the couple proceed with a trial marriage? Why or why not?
