Dont do anything. Yes speak with an L and know your rights. You are extremely emotionally attached to her and its causing you to obsess about her actions and activities.
First thing, stop snooping. You are going to drive yourself to a nervous breakdown. Second, start implementing DB immediately. Detach yourself from her emotionally. Although she may not be having an A she may start one.
Third, get back in the MBR. She is the one that fired you. You need to get her out of the Master bedroom because she is the WAS.
My WW makes a lot more than I do. But she moved out of the MBR.
Stop worrying about what she is doing and go GAL. Detach lovingly.
