ERC, I'm so sorry that you and your D are going through this. It certainly seems at time that our spouses have lost their minds that they could such little regard for their families.
Don't beat yourself up too hard for the snooping, you are human after all, but it does make you feel worse. I just got to the point where I knew he had OW and I knew that they would probably be together, but I just didn't want to know anything about it. It just made me feel worse. At this point there is nothing we can do to change their minds so we just have to change ourselves and be the best parents we can be. I have found that it really helps spending time with my Ds.
By the way my D did make the high school dance team for the 2nd year in a row! Thanks for your encouragement. We went out last night to dinner to celebrate with some of the other girls who made it and their parents. It was very nice. I'm the lucky one who gets to share this with my D. I have many positives in my life, and I'm trying to concentrate on them. I'm sure you also have several positives in your life, so take time to appreciate them. It's the best therapy for all of us going through this!
