Hi Sam - that's a great question! It thought I saw H hit rock bottom, but all he did was bounce back up. So I think being that it's different for everybody...that when it happens for real we will know.
I have also read how sometimes they will just come to you, break down and let you know. Follow the link on page 2 of my thread...he tells how he hit the bottom and looked to see if his W was there for him...she was!
The past can't be ahead of you in the future. You don't have to figure it all out, just pick a direction. What's next...I don't know but I can't wait!
