Sorry to hear about what your W is doing. I found a text last year that my W sent that said I love ya, so I know exactly how you feel. Getting kicked in the balls would feel better than seeing what you saw.
I have to agree with Coach and PDT above that you need to step back, calm down and re-evaluate your sitch. You need to do what is best for you and take emotion out of your interactions with your W from here on out. She is having her cake and eating it too and that is allowing her to do whatever she wants without taking your feelings into consideration.
