She's unhappy. Don't let her feed what you are supposed to feel. As far as you were concerned, you weren't unhappy.
"In a panic state, I gave it to my wife hoping she would read it."
Yes never give her something to read to "fix" her.
First of all, don't take the blame for everything that went wrong in the M. It takes two to tango and I'm sure once all of the rubbish that she's been spewing at you is cleared away, you'll remember that she wasn't a saint either. I'm sure there were times that she disappointed you but you didn't walk. It makes you the one with the better integrity.
Your M can be saved, but it takes time and calmness. You can do it. Have faith in yourself.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
