Sorry Dingo. I know it's tough, but I also think it's pretty normal for someone in an affair. It really is like an addiction and while she may really want to reconcile in her mind, losing that "fix" is extremely scary, as is the idea that things will go back to the same old thing. Seeing that person every day just makes it that much harder. It's like working in a bar and trying to quit drinking.
I would stop asking her about her feelings, stop trying to convince her different, or any of that. Stay focused on you, keep making positive changes, stay calm. Get some exercise and GAL hard.
She knows you want to work on the M....you don't need to tell her any more. What you need to do now is take care of you....protect yourself, set boundaries, and don't allow her to cake eat.
Hang in there buddy....I know this is really tough.
