This one -- along with the "should I take off my wedding ring?" one -- is probably THE most difficult, and intensely personal, one to answer.
I will only say that emotionally, you still sound a little "off your game," and I would tend to discourage it, as i would worry you'd be doing it for the wrong reasons. I ultimately DID decide to date -- after vociferously objecting to my wife's idea of doing it! -- after my wife and I briefly separated. And all it took was one date -- heck, one RUMOR of a date - -and my wife responded VERY forcefully, and we reconciled.
I decided only since we were separated, and only if I told my wife honestly of my intentions.
Be careful playing with fire ... cuz it WILL work.
