I'm glad things seem to be doing better... I still feel guilty to this day about what I did to my wife, but she also reminds me every time I mention it that she CHOSE to stay and pretending I was able to torture her without her consent takes away the value of that choice. If that makes sense. Your wife loves you, and you'll have to trust that as much as she (as both of you) suffers, she knows what she's doing too.
It does get better. So long as both of you are willing to try, there's hope.
