I saw that you wanted BG to tell you her secret about the son. She has been out of commission but I know what it is. The bottom line for her is this, the child is innocent. The child did not ask for any of this. When you look at the child as a separate entity from it's parents, it is easy to love them. And to welcome them into your heart in whatever capacity you choose. Good luck.
If you focus on the past, you ruin the future. You can only live for today.
