'til death do us part...

To me that means something like "until the death of our relationship causes us to part".

In your situation, there was a struggle but not death entirely. A lot of people don't have the guts/balls/whatever - to make it through the tough situation you did. It's something I hope she realizes now or someday.

There is much forgiveness in marriages all around. I'm blessed that I was forgiven for actions in my marriage that were my fault. I have an extremely bland marriage - but it's working. A lot of people expect some kind of constant whirlwind and drama and if things falter a little bit, they want out. The test we are all given in life is to make it through these things and prove ourselves that we have the strength to do it. I think you proved it and are a great example others should follow.

You really should write the book - you could showcase your struggle and outcome and help a lot of people out.
