MTS - I am really sorry about all of this. On the surface this is very disgusting.
On the DB level: Remember the "Believe none of what they say and 50% of what they do". I'd say there's a very good chance she is doing some self-convincing and self-justification for her actions. She is completely caught up on the new relationship with the OM and she wants to feel good about it.
On the spiritual level (and these are just my thoughts): The enemy will often try to masquerade as the voice of truth. That could be happening right now with your W. Another thought is this actually could be part of God's plan - He works in mysterious ways. It could be the road your W needs to go down so that she'll never go down this path again. She has to go down this path a ways to get a taste of the destruction to the point where she is completely broken and she has no choice but to turn to God. He could also be using it to bring you closer and equip you to be the strong man he needs you to be.
