The only other way I'd do it, is to tell her she has 1 week to gather herself if she doesn't feel comfortable in the master with me. And at set date (3 days, 5 days, whatever), I go back in master no matter what.
That would allow get time to get the 20thousand items she needs to get ready into some sort of bag and move them into the other room. And it would still show that I'm making the call, but is that allowing too much leniency? Kindness is weakness?
