I couldn't agree with Puppy more. It's an opportunity for a NEW relationship. If you except things as they were before, you'll likely wind up right back in divorce court.
A critical thing in rebuilding my relationship with my ex is the presumption on both our parts that this is a new relationship from the ground up. We've identified and taken steps to correct many of the issues that caused the rift. I feel assured that we are on the right path this time, and so does she. Wouldn't work any other way.
That being said, remember that she likely doesn't have the insights that you have on what's going on with the two of you (this site and a couple of others have been real eye-openers for me) so be patient, but don't cave in. And don't make any hasty decisions one way or the other until you're sure you understand and can accept the possible outcomes.
Good luck to you!
