Besides which, it's a good demonstration of the *reality* of the separation she is choosing. It's all fun and games to go out drinking and still come home to a warm body in your bed. Stop serving cake. IMHO.
While we're on the subject, I think you need to consider carefully what *she* would need to do to win *you* back, should it arise. Addressing her drinking would certainly appear on that list. Not trying to get you into the snatching-at-crumbs "hopeful" headspace; more like pointing out that being married, cherished, and forgiven is a privilege for *both* partners. Don't sell yourself short.
