Woog, I understand why you think you are done, I am right behind you. I try to think how I would react if one of my best friends would lie and treat me with disrespect (which let's face it, this is what our WAS are doing). I would avoid them like the plague. We have kids and that is what is making me hang on. I would sugest that you hang on a little longer also. You owe it to them. I am not saying forever. Give her a month in her own apt. If things don't improve, we will both file on my birthday (June 11).
