You didn't make a grave mistake - you're emotional, and it happens. Learn from it, regroup, and keep detaching.
What you have posted is similar to so many of us. My sitch has a WW who is trying to put things back together, but even knowing that what she's doing is wrong, she often shows that she can't, and won't, accept what she has done. It just isn't capable when they are in love with OM.
Shreeve, your wife is giving you TIME. Yes, it might take months or years. You might get divorced. You can't control her, you never could. Take the time, look deep, deep, deep within yourself. What do you like? What do you need to throw out? What needs exercise? Brain? Body? New experiences? New job? New skills?
Take this time. Use your time wisely. Keep posting - many find it helpful to journal and express what can't be expressed to others here. It really does help. So, so many are following you - more than you realize. Sandi is an awesome ally. Keep posting!
