Welcome to the MLC Forum! I'm very sorry that you are here, but you are going to find that we have a close knit family that will listen, provide advice/suggestions and/or just be here for support.
Tell us more about yourself and your h. Did something happen in the last 18-24 months, i.e., death of a family member, co-worker or friend, birth of a child, job loss or promotion, etc.? Does your h exhibit confusion and depression? In MLC there is some confusion and depression is the main ingredient.
Whether he is a walkaway or in MLC, you would do the same thing: leave him alone, give him time and space, only contact him in an emergency and the most important thing...be sure your assets/financials are well protected.
I have linked your thread from Newcomers over here for easy referral/reading for the posters.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
