I just finished reading a highly fascinating article from the magazine Psychology Today called Great Expectations. The basic gist of the article (which I recommend reading) is that marriage is about being married, having children, raising a family and thats all. It is not about finding your soulmate or finding the love of your life. Pure and simple, it is about being in a relationship with another person that allows one to act without pretense or without hiding who he/she is.

I would like to pose the following question:
How would one reconcile the ideas of marriage as being about being married, having children, etc. and the rabbinic idea (BT Sotah 2a) that man and woman are "designated" for each other by G-d 40 days after conception?
