You are absolutely correct!
No one said not to detach.
Not to protect oneself.
Absolutely!
That is not the issue.
PEI is detaching and is doing a great job.
This is a debate about marriage, vows, committment.

Just about every spouse on all of these forums "needs help".
Does that mean all the LBS's should walk away?

I don't think so.

My point about mental illness is that you can't blame the person who has a mental illness for their actions.
They need help without any question.
I totally understand that by walking away you feel that you are helping them.
Just don't blame them!
