Obviously this is not clear, it is K I want not the child. I will not take the child away from the father, any more than I would try and have child leave K and live with the father. However if I chose to move into a relationship with a child then I have to live with my secondary role. I would absolutely end the relationship if I thought it was detrimental to K or the child, or the child's relationship with the father. When I say a man should not expect everyone to give up what they want for their benefit I mean he should not expect his wife to be pure to his memory or move to a nunnery or whatever. A child is a different issue and their interests need to be prioritised.
