Theia, read my story. I'm kind of depressed actually that no one here told you to! Any advice I have you can see play out if you start on one of my early threads. But in short -- go dark. Go dark. Go dark. Get him out of the house as quickly as possible. Divide your finances as quickly as possible. Go dark. Go dark. Be polite, never be vengeful. Don't expect him back before 2026. Decide what you want to do from 2022 - 2026 and go do it. If he comes back, you can decide then what you want. Everything you are saying and thinking is pointless. Your H is gone. The guy you think is your H is a shark, an alien, a dark brain with no heart walking around in your H's old body. You might realize he was always that way or it might be a real crisis and he'll come out of it. You won't know for YEARS. Noticing what he does from minute to minute or day to day is like trying to watch evolution from one-celled organism to mammal. You can't do that day by day, only eon by eon. Your brain is spinning on the wrong track. Jump off!
I believe I will see the bounty of the Lord in the land of the living. Wait for the Lord with courage. Be stouthearted, and wait for the Lord.
