So did you agree to her terms? Paying her expenses to live there? (Which seems to be typical for the WAW to want H to pay for her new life.) I think you will feel strong resentment about it....if your feelings for her change. Maybe those feelings are already changing due to all you have gone through these past months. I see it happen sometimes, almost like some type of delayed reaction once the LBS starts to realize he deserves better. Sometimes it seems to be a passing emotion and sometimes it doesn't pass.
Anyway, glad the boys are going to the school you wanted them to attend.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
