Don't be obtuse. Are you a parent?
Children fantasize about their parents getting back together. Mine did.
3 years after the divorce, bizarre behaviour on the part of my ex-spouse vis-a-vis my daughter re-kindled (briefly, thank God) this kind of a fantasy.
My ex-spouse, like yourself, but for different reasons perhaps, was a proponent of soliciting the childrens' opinion on a variety of matters, most of which were beyond their grasp. This had the effect of leading the children to believe that they had the power to control. To children, and even teenagers, everything is black or white, so they thought they could decide about anything and everything. (Is a child entitled to decide whether they will or will not go to school today?) It was a lot of work to help them onto the right track.
