I agree that staying focused on your own sobriety is the most important factor for you right now - you are still so early into recovery yourself & have so many unforeseeable growth points ahead. The beauty is that the stronger your recovery, the more awareness it brings in all areas of your life & it will provide tools to help you manage all of this - things like boundary setting, detachment, etc. In the meantime, "more will be revealed", right? So all you can do is keep baby-stepping forward, you don't have to decide everything today - nor should you.
