Wolf- That is a good point. I wonder though, if both of them can be just as successful, even if they are both successful. It is possible that the person may feel that one spouse was his “zivug” and the other is more like a good friend helping him deal with his loss.
I also wonder if it’s different for men and women, since men can technically have more than one wife (implying they can potentially build a relationship with more then one person) and women can’t have more then one husband (at a time).
