Nobody has mentioned Christian therapy, it seems that it would be beneficial for both you and F? Have you read any books on living with toxic people, that might be helpful too. It hurts me that you all are in such pain, Father God, this seems like an impossible situation, but we know that you speacilize in the impossible, so I earnestly ask you to step into this situation, and show these two women how to deal with this very impossible man, please keep each one safe, and help them to recover from the damage that has been done, in Jesus mighty name, amen.
