If I took a stab at guessing... LG pretty much called it...
You got some "canned" responses in the email...
Here's where you actually KNOW it's getting better:
When she starts moving towards you, not away from you, and not "same old"...
It's like this...
The only way that your W knows that you are a better man and that you are a man that only a fool would leave, is when you make significant changes which are positive for you, in your life, you exude confidence... and it STICKS... it's permanent stuff... people around you see it, they like it, it's all good...
The only way that you will know your W is moving towards you is when... they start communicating with you on a more regular basis, they start showing curiousity at what you are doing, they start making future plans and those plans INCLUDE you... they make MC appointments so that the two of you can work on your M... that these things are consistent and persistent, so that you actually can believe that they are permanent...
There is no where near enough data... it's not that you didn't tell us enough... it's because a three hour conversation and a follow up email does not pass the consistent and persistent test...
But I do feel you are doing a great job! Keep moving forward and GAL!
