I can also vouche that my IEI-Fe Mom loved her dual 2nd husband but also took him wayyy too much for granted, often wanting "more" and still complaining even after his death, blind to much of the good he did which she relied on. There is a harsh duality lesson there for all of us about practical limits and being realistic in our expectations of others, especially those we love the most. Most people are already doing the best they can as far as they know.
