Oh, Cat, I am so sorry you are in this sitch again. Like a few others have said, don't make any rash decisions until you've taken the time for all of this to soak in and you can think more clearly. I so hate this for you. I hope that you can help him get the mental help he needs. It doesn't sound like it's about the OW or about you or your M, it sounds like it's about him and he needs some help to deal w/ his issues. I know how hard it is to stay strong during these times for you and the kids, but try to stay focused and, when you can, write it all down & sort it all through in your mind and then you can take it one step at a time.
