Your response is the reason you need to stay away from her. It is for your sake. You don't have to make a decision in a few days time. Whatever you decide will effect the rest of your life.
I don't think anyone here is going to jump you for having second thoughts about staying with her. I just wanted you to step back where your head was clear enough to make any decisions.....period. Take your time doing it.
If you don't want to invest the time, and you doubt she will put enough work into it.........those two points are pretty heavy. B/c it does take a lot of work and it almost always takes longer than the WAH thought it would.
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!
