I gave myself a one year time line. Currently five months in to the one year. I too am really not sure what I am going to do. I am preparing for the end (quietly). I keep thinking, why wait? What will it accomplish? Well, maybe the "what-if's" will have diminished (either way), but in the mean while, I am being ultra observant and trying to really look at all that is going on, reading here, seeing a counselor, saving money, researching housing options - etc.
I am not a very patient person, so this is testing my resolve greatly. But I will give it the additional 7 months and see where everything is at that time. I guess the timeline keeps me in check.
Sorry for rambling. Just wanted to let you know I am exactly where you are also.
