You sound great, glad things are settling down and SO doesn't sound quite as crazy.
But, for pete's sake, you don't need to be managing his R with OW for him. Get your stuff out. I'm not sure what you hope to accomplish by trying. If your theory is correct, you have no idea if leaving your furniture there would prolong or shorten the R. No one does.
Get your stuff while he is sane and calm. The sh*t will hit the fan when the OW R reaches a crisis point again.
