Very well done Gordie. That is indeed quite a development. She acknowledges her childhood trauma and is telling you about it. I would put that in the positive colum.
Her talking about how her issues damaged your M, a couple of things leap to mind. Using the word damaged not destroyed, might give an indication of the severity she perceives. Also it appears she is showing some responsibility toward what has transpired.
I have similar thoughts as sjohns6 towards keeping your distance and not telling her where you are going. At some point things will have to change. However for now probably a wait and see approach is best. Get some more consistent actions. (Wow, a kiss on the lips! )
You are doing great. Stay the path and keep those pesky expectations low.
How are things between W and D19 working out?
Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
