Julie, you being wise to what's really going on does give you a leg up in the situation. So many people refuse to see the truth.
NYGal, I do believe that your W saying she wants more time alone means that the affair with OW hasn't ran its course yet. I do believe it will and I do believe she'll want you back when it does. The important question, however, is will you want her? I've read so many of your threads that I feel I've gotten to know you and your W. What kind of people you are. Let me tell you....you can do way better. You're a much better person than she is. I don't think you're capable of dishing out as much cruelty to another person as she has done to you. My two cents, you should be the one telling her to get lost. With that said, if you want her, then I want you to get her so I'd give any advice I can to help you get what you want.
