It sounds like we are in very similar places. I have finally been able to get OW for the most part out of our bedroom. I did it by reclaiming it - frequently.
This may seem totally crazy, but I also plan on doing a sage burning in the whole house to cleanse it for negative energy.
And I really recommend MC. We go weekly to a DB counselor and it helps me organize my thoughts and concerns and present them there instead of ambushing H on a frequent basis. When we go to MC, he is prepared for uncomfortable conversations and knows that they have a limit. He expressed in our last session that he appreciates how I have backed off and that it helps him be more open.
