What happens to unhealed fearful avoidants when they are old and alone?
You've left a long trail of hurt, pain, and blame. You never experienced real love, just dopamine. When things got real, got scary, you ran. You abandoned. You used people for sex to feel better about yourself. You used people for dopamine because it was easy.
You think you know what love is but you don't, you've spent a lifetime on the outside looking in. It's not your fault because you always blamed the other person, because it was how you coped.
You can't accept you were your own worst enemy because admitting that means you have to acknowledge it was you who ruined your life and it's your fault you devastated everyone in your path. So what's left? You do as you always did. You lie to yourself and then you die alone. Even if you managed to hang on to someone you couldn't drive away, you still die alone.
