Don't play games with her. If she asks a question about business (selling the house, etc.) then answer that question and add nothing else. If you do not see the importance, ignore it. In case of the flowers, just a quick TM saying "It doesn't matter to me" and leave it at that. Don't sweat the small stuff.

I think you really need to GAL and find yourself as an individual. Become more interesting. Sounds as if you entire life has been consumed with your W and you lost your identity. I'm not saying that you should D, just saying to focus on yourself and start living instead of burrying yourself in the death of a M.

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!
