Love: Deep in the Well

Have you ever wondered if love is a real thing? Is it something us humans just use to classify a sort of strong feelings towards another being? Or is it a chemical (dopamine) induced feeling that traps us into this cage and is an emotional drag just to get out of? How can one word have so many meanings to it? That's why I enjoy the word love. In Greek, it has many different forms and it's beautiful <3. But what I question is if love is truly real. Of course I know it exists, but does it really? Or is it simply what were "supposed" to do? Love is deep. And I'm not sure I have a handle on it quite yet.
