Thanks for the feedback everyone. Here is an update:
First, let me point out that my wife is an EXTREMELY analytical and level-headed woman with A LOT of integrity. For her to be put in this place means that she was near or at rock bottom mentally.
We talked a lot these past few days. We opened up about our true feelings towards each other, and I've even come to the sad but true conclusion that I was not really in love with her. After all, if I was truly in love, I would not have been so easily be able to justify the numerous times I've betrayed her.
