Codependency Support Group
Codependency is defined as someone who exhibits too much, and often inappropriate, caring for another person's struggles. A codependent person may try to change, or feel shame about their most private thoughts and feelings if they conflict with the other person's struggles. If you are on a journey towards self-love, this support group is for you. Join us and find others...

You can't control others, how they act or what they think. So don't try. Say your peace and be done with it. You may or may not get approval. If Simon is who you want to be with, it is YOUR CHOICE!
You may even need to speak with a professional about your situation, just to get an outsider's opinion (like you are doing now). He/she may give you insight you hadn't considered before. I'm no professional therapist - just a codependent person who's learned a lot about this mindset.
