Hadlee, often the sentiment around here is that the leaving spouse should suffer all displacement, not the LBS. Whether that's saying "If you want to leave, you will need to leave the bedroom" or saying the same about the house. I don't know if vets will chime in on this as it pertains to your situation specifically and I'm not one, but just a thought before you take any action either way.
