You didn't have to tell me this, it's abundantly obvious that you've never had real love.
You would give your life for a selfish moment, but wouldn't give up a paycheck to be with someone irreplaceable.
It's why you've probably never known love, and if you don't change, never will. I hope you'll change. This happy thing totally fucking rocks.
I'm very happy. Never been this happy, in fact. I can make more money, but we can't replace each other. People are not interchangeable.
We have everything we need. In fact we're downsizing our possessions. We have wonderful friends. We have our little getaway cabin at our nudist campground. We have excellent health insurance, so an illness won't bankrupt us. We aren't life proof, but life will always find a way to fuck you up. Get on with living it while you can.
