So maybe taking control of my finances is both the most difficult, and the most important thing I can do to assert my independance.
As JJ wrote, M is a mix of different ties... the two biggest being emotional and financial. If you can't "control" the emotional aspect, you can at least try to gain control of the financial. That way, you'll have a more solid base to work on the emotional. Good luck. I'm battling the "financial demon" myself.
