If you can sleep together in peace, you can live life together the same way.
A major loss
Many of us will experience some kind of profound loss while in a serious relationship. This could be the death of a loved one, a crushing layoff from your dream job, or a big missed opportunity of some kind. Loss is just a sucky inevitability in life. But it's also a great indicator of the kind of partner you've got.
When you're down for the count, can the person you're with pull through and be the rock you so desperately need? Can he or she be your shoulder to cry on and never judge you for your vulnerabilities?
When the shoe's on the other foot and you're being the supportive one, does your S.O. accept your love? Or do you get shut out and pushed away? At the end of this experience, whether you should marry the person you're with should be crystal clear.
