Fib, part of this undertaking of yours, due to State laws, etc... comes with the unfortunate side affect of having to live with the insanity all around you and in your daily life. I do not envy you on that my friend.
However, you have to continue to "be the bigger man" as you have tried to do all along. It is not about her, it is about you and letting yourself down. Through reading your stuff I know how you end up feeling when you allow yourself to fall into the silly little traps that she lays before you. All designed to get you to make a rash decision to end the chaos and make HER life easier.
FIB, you can see the light at this point. It is in the distance and although it looks so far away, it is really so much closer than you think. Just stay focused buddy, your amazing life is only a short time away here.
