If your ok just letting her do whatever she wants then you really, really have to let her go emotionally. Based on your posting about the other morning and your reaction I don't think you are there yet. Just my observation.
I snooped when my W first moved out and then I stopped. As time went on I no longer felt the urge however I knew I wasn't detached because their were times when she would say something to me and it impacted me emotionally and I felt that sensation in my stomach.
As time goes on you your path will become more clear. I was lucky in many respects that my W moved out 3 weeks after BD so I didn't have to see her or talk to her every day which helped me move forward. As you grow stronger and become more confident what you are willing to accept and not accept will change. It might be hard to see now but it will. Once you get to that point you will have some choices to make.
I don't think your W is going to push for it, just my opinion. In my opinion what happens next will be determined by you, your boundaries, what your willing to accept and how long you will accept it for. I think your W is perfectly happy with the situation and how it is.
I also found it interesting at your MC session that you spoke about what you needed change and there was nothing at all about your W's behavior and the work she needed to do. We only know what you post though so maybe you just left that out
