Just wanted to restate what PL said, and it's something I have said a LOT around here, we ALL had reason enough to say f--k you to our spouses on day one of this sitch. Finding something out on day 232 that only reaffirms our reasons we had since day one doesn't change anything unless we were led to believe things had fundamentally changed. In your sitch, things HAVE recently fundamentally changed, sadly for the worse in terms of her trip and physical interaction with OM, but you knew that so this image you now have does not provide you with anything other than a living, breathing tool of pain to use on yourself.
I know you didn't go looking for this, but now that you saw it, you need to do your best to purge it and understand that your reasons to continue, should you decide to do so, have not changed, nor has the basic state of the sitch.
