I recall a few arguments that my W and I had where she demanded that I leave "MY bed." She said it was hers because she owned it before we married, therefore it was her property.
The next day, I told her that we were either going to sell it and buy another one that we would call "OUR bed," or she was going to promise to not pull that sh!t anymore. She promised.
There have been times where she has asked me to leave "our bedroom" since then, and sometimes I stay, sometimes I leave (for my own reasons). But she hasn't called it "her" bed.
