Moving her stuff out into the guest room seemed like a waste of time. she just turned around and moved everything right back into the MBR. What did that action tell her? I don't know. What did it do? I have no idea. What was the point? I really don't know. I just followed the advice here and it didn't seem very beneficial guys...

I went and bought a door knob with a lock this morning with the intention of putting her stuff back out into the guest room again and locking her out of the MBR. I still don't know if that's the best course of action. Please help
