I have a life that no one knows about
Whats special about this life no one knows about?
It's how I want it to be and nobody will try and change this goal to fit others
It's good to keep things you don't want to share to yourself. Just don't make others feel like they're being left out of your secret life or your relationship might suffer.
What's wrong with having a secret life?
Like I said, nothing wrong with keeping some things to yourself, but when you withhold most of yourself, life gets pretty lonely. If you're extremely uncomfortable revealing yourself to others, you might want to consider counseling.
