One thing you DO need to do immediately is to seek a L and ask about your rights---first thing tomorrow morning. Knowledge is power. Seeking a L is necessary to protect yourself. It does not necessarily mean that a D is in the works or that you're moving out. Do not say a peep to W about seeing a L. It is your private business.
The main thing is that you continue to stay in the house and sleep in the MBR. It is your house. If W has a problem with it, she needs to be the one to leave the house.
