First positive: you set the boundary of needing to know where your kid is, and she respected it. Do not mess it up by using the information to your advantage. Now that you have it, I would recommend you mention to her that you have put the address in a safe place so that if there is ever an emergency and you need to get to your kid, you know how to get there.
Second positive: she provided you with a list of all the things you need to work on in yourself.
Amen on the positives, Mike. I felt relieved after that conversation, actually, because I saw a glimpse of the woman I fell in love with amidst all this chaos. It was a mild reprieve with some rays of hope. One thing about the conversation that indicates the extreme difficulty (or perhaps impossibility) of her ever wanting this relationship again is the frequent statement where she says that she is not interested in seeing if I'm over porn or not. I also posted a similar entry at the porn addiction recover forum I participate in to hopefully get their feedback on what this conversation means from the POV of the wife of a porn addict.
