Don't misunderstand this one

“Stay single.
I only say this because when you’re young and in love, everyone thinks they’re the exception. Sure maybe mom and dad slept in separate beds and then separate rooms, maybe the older couples you know bicker or fight, maybe they don’t talk at all if they ever did.
At your age, you can’t imagine it will ever be you, but it will be. Which is bad enough but what’s ever worse is how much you’ll feel like a failure because when the person who knows you best loses interest, that really takes something out of you—like surgery almost—and you really start to wonder if you’ll ever be whole again.”
