This post is stating the obvious, but there seems to be a need.
Expressing insecurity about looks or relationship status undermines whatever it is you want to build. Alpha men and women are confident/ confident men and women are alpha. Get all needy for re-assurance and clingy for re-bonding and you push away that which you seek.
Chill, and expect it. And if you honestly can’t controll your fear, bottle it up and wait it out. It is yours. Don’t bug people with it.
