I think the key here is giving your W a glimpse of life without you in it. That's why detaching is so important.
Yes you will feel guilty for doing it - it feels like you're saying "Fine. If that's the way you want it, then I don't care..." But then after a week or so you'll be doing your own stuff and setting your own goals.
One post on the quotes page is "You're never more attractive than when you're walking away." (ish - can't remember it exactly). You must let her realise what losing you means.

Keep posting and asking for advice!
