You might be onto something here, as that's what the research seems to indicate. 79% of people aren't looking for a committed relationship, BUT, I will say there are many, many other forms of love beyond a monogamous marriage. People find love in family, friendships, hobbies, work, and a plethora of other things that give their lives meaning. It seems a little short-sighted to try to distill the expansive varieties of the experience of love down to romantic relationships and marriage.
