"I reject ... this modern fascination with 'discerning who[m] God wants you to marry.' Obviously we want to discern God’s will in all things to the best of our ability, but what exactly are we discerning and how precise can we be with our discernment? In my extensive reading of history, here is how it has always been done:
"The discernment process has always been whether or not to get married, not to whom one gets married.
"That is, in the Middle Ages and beyond there is a great focus in spiritual writings on discerning whether you are called to celibacy or the married state. But once one discerns they are called to the married life, there is almost nothing like we see nowadays about 'figuring out who[m] God wants you to marry.' There is a lot written, however, about how to best “pick” your spouse. That is to say, the choice of a spouse was not seen as a matter of God’s will but as a matter of human prudence, much like picking a good house or picking a good piece of fruit from the market. Love was never seen to be the basis for a marriage, though it was sought after to arise after the fact by mutual affection and sharing of a common life. The woman (or man) who married simply out of love was considered a fool, and there are no records that I know of any person being taught to ask who God wanted them to marry. It was seen as something that a person was supposed to use their human judgment (common sense) on and not try to be all vocationally oriented with. A man chose a wife based on several factors, and once the marriage was consummated, love was seen to be a worthy thing that could grow on the basis of that union, but it was not deemed essential. My RCIA classes always marvel when we get to the class on the Sacrament of Matrimony and they see that 'love' is not required for either the form or matter of the sacrament."
