Just try to remember that you're not trying to R with THIS woman. You're trying to ready yourself for a better relationship in the future with someone. It's certainly possible that once you get there, you won't want anything to do with the person your W has become. So don't worry about it!
By the way, I'm not sure which way is "easier" - DBing while staying together with plans to separate or ripping off the bandaid and DBing while separated. Maybe both suck equally?
