How about simply being direct and report what is going on?
"H, I want a separation. Being more into the M than you are simply does not interest me anymore. I want a much better R than you can offer me. I'm moving to the other room as soon as I get it organized. Anyway, the idea is that it will be a true separation as when we were separated before. So, for instance, you're in charge of your own laundry. But, lol, I'll be happy to trade laundry for yard work."
