Write a letter. Don’t send it. Whatever happened, whatever your intent, you hurt her and worse, it became a legal matter. Step away. You need to make sure it doesn’t happen in future relationships. Seek counseling. Be kind to yourself by allowing you to grow and mature from this experience.

Why would you even want to stay with and create a life with this man? Why do you need his validation that he doesn’t care? Staying with this sort if person will cause a lifetime of pain. I know from my own experience. Please find a way to leave. Don’t accept a ring that will remind you of this frustrating period of limbo. And don’t move in until the ring is ON your finger.
