I wonder how the story's gonna go from here. The usual would be a new purpose and recovery, maybe he can be open and show his scars and reveal his past? Since we havent opened that can of worms yet.
Maybe he could divorce her and then she recovers in a distant town/country where they dont know her heritage?
But at this point she wont care about anything
The unusual way would be her getting a new romantic interest or a good friend and leaving ml. Or that she actually goes through and successfully kills herself. But dang we not even at ch 20 yet.
