Best part of my now nearly vanisher: I don't have to clean up all the crap he left lying around. Trash, plates, socks, shoes, clothes, dirty pans, stiff all over the counters.
And I agree about the dark cloud. I thought I was unhappy, but I was only unhappy because I had someone gaslighting me, and I didn't realize it. I was amazed at how much I improved when my Wallower moved out.
