She's making a series of bad choices and the worst one is she's picking some OM over her daughter. She might also work on losing her job. I would go with Bworl on getting separation agreement in place.
I'm not sure I would answer "No" to the divorce question or "yes" to the "do you still love me?" question. I don't think it's that easy and it shouldn't be for her. I wouldn't give her any indication where you are at emotionally. She isn't entitled to that. I would tell her, "Now is not the best time to answer those questions. "I don't know", is the best choice at the moment. "Put yourself in my shoes. What would you do if I repeatedly cheated on you? What would I be trying again for?"
You will have to deal with MIL. She's not going to be able to be your roomie for that much longer, can she? You need space and you don't need someone that is a conduit to your wife's ears.
You cannot be lonely if you like the person you're alone with. Dr. Wayne Dyer
