Don't bring up R. Just accept the D for now. How is her relationship with your son? Do they have a bond? Because if not MC to get along is not going to appeal to her either.
When she says that you are not a "believer" I am assuming that you are speaking religious terms....if so...have you ever heard of retrouvaille? Because if she is a "believer" then she would not want to rush into a divorce. It might worth it for you to look up retrouvaille and maybe approach her with that as opposed to MC. Just a thought...
