Introversion and extroversion are personality types. They can’t be changed. They’re fundamental to who a person is and how that person processes information. It’s not merely about being social vs. not being as social. Introverts can be socially assertive and outgoing without becoming an extrovert. Introverts are predisposed to social anxiety. That’s something that must be overcome. It’s an extrovert’s world, and introverts need to do quite a lot in order to adapt and become socially successful within it.

They’re probably never going to be actively hurt as all their focus is on how to get pleasure right now. But letting them know just how disgusted you are by them and how you never want them in your life and there is no caring for them whatsoever. And being happy and fulfilled and living your best life without them and not needing them in any way hurts deeply on a subconscious level and just keeps the internal pain of not deserving any love deeper. It further stunts them and keeps them incapable of living a good life. That’s quite a good revenge, at least for me. The more I heal and the happier I am, the further away I am from the emptiness and void and shallowness they live in. It feels great.
