HS, Just read through your sitch. Mine is similar to yours in that there's no OM or A. Wife left because of my depression issues.
I see that there's one thing thats going for you. Is this the first time your W left? If thats the case, you have an awesome opportunity to look at yourself, analyze what you can do better and improve. When your W sees them, she definitely will come back. My W did that in 2009 when she left for 6 months. Only problem was that at the time i did not have help of sites like this. I did not forge a tighter bond with my W after she came back. Our relationship got strained and now we are at the doorsteps of D.
So, remember, make that change permanent and when your W starts warming up to you and you guys get together, make sure that you make that bond with your W better and tighter.
