Update:

Now she is telling me she will fight to stay in her room. Physically if necessary. Well I assume that's what she means. She said she won't use words this time, she will defend her territory.

Threatening to try and take everything off me in court etc etc. How do I disengage from this conflict? If I go into the bedroom, it looks as though it will be a physical confrontation, which I don't want. Unfortunately all those months I spent looking after D in another rom have worked against me, and WW thinks she is entitled to her own room/bathroom. Couldn't have had this issue in the old house, wasn't big enough.

I can't mentally face going into the spare room again. My D's room is bad enough when my D is sleeping in the MBR with WW.

Now she just sent me another link on marital rape. This just feels ridiculous.
