Yes in fact I would take it a step further...after she is all set and allowed to stay in the country...I would make sure it's YOU that says something like this to her... "Okay now that you're all set I want to make it clear that this doesn't mean we are back together. I did this because I care for you but it is clear to me at this point that we should lead separate lives."
Basically you want to make it sound like you are fine with, and actually in agreement with, not having a true husband/wife relationship. Using your own choice of words of course. This throws the WAW for a loop. It did with mine. Once I supported her decision to divorce and acted like I agreed with it...I found out months later from WAW that this pissed her off. Almost as if I stripped her of power by agreeing with her. Again, it might not help you get back to where you truly want to be but if makes you appear strong to her and no matter what happens it helps you move on because you'd have to accept the split anyway...so it's a win/win for you whether it "works" or not.
