Hey Free, I'm here. Sleeping arrangements, there are many solutions. The solution has to support your goal. What is your goal? If it is to get her out of the room but keep her in the house, install a lock on the bedroom door and keep the room always locked. Or you could get rid of the bed and replace it with a single bed. You could replace the couch with a bed for her.
I don't know how you can not talk to her about the OM. I would have talked to her the second I found out. Do you think she is having second thoughts? Maybe she wants to get back together with you? Is that possible? Could you have the OM throw her under the bus? Would she sober up emotionally then? Could you go to OM and tell him to drop your wife now and forever or you are going to HR and threaten them with a lawsuit. If he says your wife will also get fired, look him in the eye and tell him you don't give a $hit but he'll be living with mommy forever.
What do you want? It's not clear to me. If you might want to stay married then talk to your wife. Maybe after she knows the sleeping arrangement will work out. You wanted advice so here is what I would do, talk to your wife, tell her what you know, it''s best for the both of you to deal with it honestly. That's all I got.
