You really have to let me fight my own battles. You can't constantly second-guess me and try to protect me. It's stifling, Christian. I'll never flourish with your incessant interference. I need some freedom. I wouldn't dream of meddling in your affairs.
... if we are to have any hope of a future together, you have to trust me and trust my judgment. Yes, I'll get it wrong sometimes—I'll make mistakes, but I have to learn.
... I know you want to control everything, and I understand why, but you can't. It's an impossible goal... you have to learn to let go.
