I think you're spot on CTH. When you start these TALKS and whatnot again, it does set the time clock back. That's why it's good to go cold turkey, no contact and keep it up.
My story is the same. I should have just walked away for good last year instead of spending all this year working and talking and etc only to be met with the same BS by my stbx. I lost another year but what can you do? Just move on.
