I think personally it's a foolish feeling... & it's "made-up" by humans really. I mean, if there weren't any people on Earth, then
there wouldn't be "love".
Another question, would you "marry for love" or what else like someone's financial support or whatever...?
Love does not physically co-exist with us, it is just a feeling.
I would only marry for love, I would not be with someone who I couldn't stand being around for the sake of money or support. I'm a bit misanthropic as it is, so even when it comes to befriending and/or dating people, I make the decision of whether I can see myself enjoying their company and not wanting to constantly leave them to be alone.
It's "foolish"?!? Why on EARTH would you say that? Do you have no family, no parents, no children, no siblings, no aunts, uncles, nieces, nephews, grandparents, someone you care about, anyone at all???
