Wow. I just read this current thread. Unbelievable. Having a live-in MLCer for 5 years sounds just unbearable. I've been living with my MLCer for a little over 2 years, I can't imagine what you've been through. You have the patience of a saint.
May I ask, where does he physically reside in the house? How often does he interact with your children? Does he leave the house often? What is an average day like?
You can feel crazy living in their insane life that seems totally normal to them. Hugs to you.
