Hi, your mother in law really is a peice of work! Why on earth you are giving her head space? You are challenging the way she has rearranged her strange little world, and it would be so much easier if you could revert to being the way she thinks you ought to be! Otherwise she might have to think
These MLC people usually had poor parenting.
I certainly would not tell your h. He has enough to deal with managing the endgame of his MLC. And as for following your MIL's advice. Well you don't seem crazy to me, but if you did I would have to wonder. It is nothing to do with her. It was a peice of gross and insensitive impertinence to on her part to intervene and the only thing to do is ignore it,and try to feel compassion for someone with so litle sense.
