Looking at my W now I'm actually repulsed at times by who she is currently
I can relate. I've put a lot of thought into this very thing. However, the thing is, we aren't the same people we were five, 10, etc., years ago. Not at all. Sure, fundamentally, but we change/grow/regress over time...even our wives. I can't remember the person I was back then, can you? Our wives evolved into who they are and its part of their makeup/code. It is who they are now.
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
