These answers read like poetry. You are all very talented!
You all are saying it so well, that I'm off the hook and will just add one or two little "alerts" that you have a true love bond:
You feel at perfect liberty and comfort to engage your loved one in arguments, to rage, throw a fit, complain, yell, and ask for your space...because you know from experience that no matter how badly you behave, his love is as close to unconditional as a human can ever have to another who was not raised in his household, and that he will not forsake you nor you him.
There are only five people in the world I feel comfortable having repeated vicious arguments with: two are my parents, two are my siblings, and one is my baby boy.
It almost feels as thought we are bound by adoption or some other non-blood kin tie. You do not even mentally conceive of him as "another person," but as kin to your heart.
When you say "people," it never occurs to you to mean HIM (or her, depending on who your loved one is
), because his spirit exists separate from the rest of the world; it hovers next to you at all times and lives on the inside of your brain. He is a blazing warm presence always in the corners of your mind, and all is well with the world as long as he is somewhere out there, alive and simply existing.
