1. Move home, today. 2. Kick OM out. Immidiately after you move home. 3. Demand No Contact with OM. 4. If she doesn't stop contact, she needs to leave the house, immidiately.
This will command the respect you deserve. That is your home that she's allowing another man to sleep in. If she wants to have a PA/roomate/whateverlameexcuse then she can do that somewhere else. From there, you can begin DB. Until then, you're SOL.
