Oh, but let me clearify something about telling her that you agree that she should be with OM......the most important part is that you let her know that it is b/c you basically want to be single again! If she thought that you would be pinning away for her, then she would have her cake and eat it too.
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!
