I'm curious as to what ideas Mrs. Thinker has to improve your situation. We've watched Thinker try many things, and we've seen some improvements and some errors. What if Thinker does nothing? What if this is Mrs. Thinker's problem to solve? What ideas does she have for making things better?
Given the situation as it is: they live in the same house and love the same children. She has no feelings for him and does not choose to have feelings for him. He is not leaving his home; she is not leaving her home. Given this gordian knot, what is her solution?
