I would say, if you don't want this, then why should you be the one to go to her and ask how things are going to proceed? Let her come to you and tell you. Let her do the work.
And in the meantime, find things to do that will make you happy. Something that helped me is hanging out with old friends. People that grew up with me and really know me. Those kinds of things can take you back to a time when you were happy without your spouse. You had a life before her.
