She is all over the place. At one point in the same convo she said I'm the perfect man for her, and that she will always know she at least had one true love. She also laughed that someday she will probably be stalking me and my happy new family... Its hard to be mad or hurt when none of it is even logical.
Your wife sounds like she's 25-going-on-15. Did she not have a chance to live out her 18-24 years or something? She sounds like he's having a "quarter-life-crisis."
btw, even if you end up choosing a mediator, you ABSOLUTELY should also hire your own attorney to look over any final agreement before signing it. Whether or not your wife does is up to her.
