I respect your point of view. But to fully understand, then you need to consider this. Jay was actually the illusion. Now the children have their true parent Joy and their mom. Yes, they have two mothers, and other families have a father and mother. So what? As for Joy’s ex-wife, I think we should not assume she is unhappy. If anything, she is probably happy she now knows the truth and is able to parent with the authentic person who engendered her children.
