Please be extremely hesitant about saying anything that sounds like an ultimatum to her. I am concerned things may backfire on you, and that's why I encourage you to read the links. You may want to do some research on MLC, too.
When you can look inward and see what you need to do to improve yourself, you can set personal goals to keep you on track. Then decide or figure how you can obtain those goals. You can read information or look for personal growth tapes/classes or whatever it is you feel you need.
What about your parents and your childhood? Do you have a good relationship with them?
What do you like to do for fun? What gives you inspiration?
I think we can learn from each other here on the board. So, stick with it.
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!
