Arsh, I don't think we're allowed to post links here but I finally found one fairly legitimate-looking website that says "Research suggests that 82% of people experiencing a crisis during midlife regret divorcing and leaving their families based on irrational thinking about what their life is like at midlife." There are no citations for the 'research' so we don't know how it was conducted or whether it's valid, but that's at least some kind of statistic.. A lot of people here sound like they don't want their spouses back after this has gone on long enough, but if you still want yours back, it sounds like there's a high chance you'll have this opportunity. Perhaps that helps just a little.
