Has she moved out yet? Are you physically separated or is this some wording? Whatever you do give her A LOT of leash. Trying to pull her back will only make her fight harder to get away. You don't want that. You want to let her go....
Unfortunately, intuition is usually right and I think you even have evidence supporting this. I don't think you need to confront her. You need to start working on detaching and focusing on YOU.
Go to the gym, buy some new clothes, make sure your hair looks great, go to the mall and find a new colonge, join a class in something you've always wanted to do, start GALing and doing some 180s.
So, share with me your list of what you plan to start doing for YOU this week....
There is no arriving, ever. It is all a continual becoming.
