Brian, let me make a suggestion and do with it as you wish.
Get your wife a card, something simple with no love quotes in it. More along the lines of a friendship card. Inside write her a note, something along the lines of:
XXX, I read the lyrics to the song you told me about and I think I understand. I just want you to find yourself again and be happy. I will support you in whatever way you need me to in order to help you find your way. Part of who we are, our core is caring about each others well being and it is important to me that you find your happiness.
Simple, to the point, shows you listened, and takes the pressure off of her about you. This is the part of your marriage where you get to sacrifice what you think you need and what you think you want and show your wife just how much love you have in your heart for her. The day you know you love your wife, is the day that you recognize that her happiness, even if it is without you, is the most important thing in the world to you.

Brian,
Old thread locker has given you a good suggestion.
Take him up on it.

Ian. Lodo stole the first drink because you weren't ready. Brian, I only gave you "squirt" because you type too slow, if you had gotten the "jack" your reaction time would have been even slower..so I was just lookin out for you..
