If you're married, you'll quickly realize the correct answer

I do like the previous suggestions of running a smaller big ring if that helps accomodate a chainguard. 46T and 48T rings in 110 BCD are easy to find, and your wife may not even notice the difference once you've readjusted the front derailleur.
