I'm pretty close to where you are at the moment 2s2q. Keep the expectations down, respond to your wife's needs (if she wants it, she wants it), ENJOY IT (!) and go back to living your own life afterwards.

You'll have to fight thoughts for a couple of days but you know what has worked and you know what needs to be done. Have fun with it.
