MWG's Husband is definately MLC. His depression and mood swings and the things he comes out with are classic.
Dar, I know I am not a professional, and I do not claim to know everything.... but I can tell you from your posts here and from what I do know about your situation that your Husband may be in a crisis of sorts, but it is not MLC.
There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
