I know this sounds awful, but from what I've read from many others, its best to treat it like the wife you remember died, and so did that marriage. Your waiting for a new wife to come into the picture with a whole new marriage. I like the aliens kidnapped my spouse version more thou. Either way, you get the point, the old wife is NEVER coming back, maybe you need to look at your wife and act like your a friendly stranger to detach. I know that's not easy either, but its true. Just say to yourself "Who is that woman?, cause its not my wife."
