KF: How do I bust my divorce if every time something positive happens, like her wanting to see me, I have to take it as a negative?
If you do want to attempt to ride it out, you do have to keep a positive, yet realistic mental attitude.
Go with your four point plan above (maybe 3 weeks, not a month), but also do not allow yourself to think she may not be dating.
Consider that she may be dating and that you are making changes that COULD change that tide. You can also set a time limit in your own mind that you don't tell her about so that you know you will not spend YEARS working on this without any sign of progress.
