Going dark is a tool that is often touted as a panacea, but explanations of its purposes seem to be lacking or vague at best, especially as applied to the MLC sitch.
Are you wanting to go dark to protect yourself and/or your family, or are you doing it specifically to get a reaction out of your H?
Going dark should be FOR YOU...reserved for times like when your spouse goes ape$#!+ and you just can't handle it anymore, or if (heaven forbid) the children's immediate welfare is at stake.
Doing it specifically to get a desired reaction from your MLCer might work in the short haul, but in the long haul will NOT make them look at themselves any faster, could actually extend their stay in la-la land, and may wind up causing you pain when they don't act according to your expectations.
Just my 2 cents, spoken from experience....
PATIENCE AND FORTITUDE CONQUER ALL THINGS. -Ralph Waldo Emerson
DBing and MLC take their toll....Please provide exact CHANGE. -Jimbo
