Is it Ever Really About Love?

After reading A Nectar in a Sieve, (i know it sounds boring just go with me on this)
I have come to the conclusion that people marry who, when or why because of their culture/environment constantly influencing them. People are always bias towards good looks, no matter what they tell you or themselves. I catch myself doing that all the time, what can I say? I'm only human, I am not just a blog looking into the world like a kaleidoscope, constantly changing my view. Also, people especially women, are constantly, drilled or possibly harassed by their peers or their parents on when they will be betrothed/hitched/what-have-you, because women need to get married just in time to be a "HOT MOM", and then some. Then, there's always why. Oh there are numerous reasons; goldiggers that can be on either end (just look at Madonna's husband), shame, hopelessness, even pitty, and sometimes because you think you love someone.
This brings me best to the question: Is it ever really about love?
