Living with a MLCer is the most difficult thing you will EVER do. It requires patience, tongue biting, detatchment in a major way, more tongue biting, patience, patience, and a great support system to help you stay sane.
The support system is here, the other stuff you have to do for yourself, but it can be done.
"Acceptance doesn't mean resignation. It means understanding that something is what it is and there's got to be a way through it."--Michael J. Fox
