In my experience your W will push for D once she is comfortable with OM. As long as him or another OM is in the picture you are firmly plan B. I am generalizing here but most women won't jump ship unless they are confident they have a place to land. My XW waited 8 months to bring up moving forward with D, she was dating the moment she moved out of the house and only pushed it forward when she found someone she was comfortable with.
