I certainly won't claim anything is busted, but I have felt it was hopeless and over several times. I've gone to see an attorney...then reconsidered and not started the D myself.
At first you just decide to wait for a while, then, just when I'm ready to throw in the towel something happens that helped me decide to give it one more day...or another week.
It really did become a day-to-day thing for a long while. Now things are happening more frequently. Still way too slow IMO, and maybe too late, but they are happening.
One thing that helped me was realizing early on, that W wasn't the only one who could walk away. After my first visit to the L, I saw pretty quickly that I'd be better off financially if I just got the divorce.
Somehow that made me feel a little better. I told myself that it was my choice whether to put up with this crap everyday. I can always throw in the towel...maybe I will do that....tomorrow.
Hey, you deal with it the best way you can. Or you walk away. Either decision is right IMO. No one should have to put up with some of this stuff.
