why would you get married?

[Bond]

Sorry, I was being a bit sarcastic in my answer. Here's what I really I think:

I view all the grand choices of life (the relationship you choose with your family, whom you associate with, your profession, and your spouse) as a road to self-actualization, that is, the pinnacle of one's existence.

While I do think one can lead a very meaningful and purposeful life without a spouse, I do not believe that it will be a fully realized life. To your family, you have given your love, to your associates and friends, you have given your trust, to your profession, you have given your intellect, and to your spouse, you have given your soul.
