Quote: She basically concluded that there was too much stress in her life, most of it caused by my ex, my kids, her decision to move from her perfect career and her perfect house in her perfect town, to this job/house/city she hates.
The theme of leaving her perfect life behind for a town, etc. that she hates seems to come up again and again. I'm sure you had a reason to move to your new home, but how important was it? When you discuss your job, you don't sound that enthusiastic about it, so I assume it's not your "dream" job.... How happy would she be if you offered to move back to her old dream town and job?
I'm a bit scatter-brained, so forgive me if I've asked you a form of this question before...
