>> Commitment has made a difference. In interviews with some women who have been married 20 years or more after living with their spouse first, firm belief in a future together was a common theme. Personal opinion: I think this is the common thread. If living together is seen as a "trial period", it could ingrain the idea that "he/she is not committed to me, and will stay only as long as I please him/her" into the relationship. That could lead to long-term mistrust. In my own marriage, my wife and I continually express our determination to stay married until death. This makes being vulnerable much easier, because I don't fear rejection. Indeed, I'd say that's the biggest difference for me between marriage and dating.
