I've learned one small thing about love in my short life.
"If you love something, let it go. If it never comes back, it was never yours. If it comes back, its yours forever."
Not that I am anywhere NEAR qualified for marital advice... I would say a trial separation, don't pressure her to come back. Let her decide when she sees how its like without you there.
It's how I got one of my best friends to come back. After a sexual indiscretion with her, she didn't want to talk to me. I apologized all the time, tried to win her back. Then I remembered that quote. A couple weeks later... got a text from her and now we are friends again.
If you love your wife, you'll want her happy, no matter if you can do that for her or not. Its tough, as I'm sure you know. Do the trial separation, see how it plays out.
