My daughter's ex-husband has it- he has a successful music/recording business and still performs. He wanted a family, and she gave him two kids, but he couldn't hack it in a real family fulltime- he's basically a loner. Well, at least he pays the $$$$ child support every month-
I was married to a bipolar lady for about a year- it was hell- I had to get out before I ended up in the cracker factory. IMO, people with mental issues, usually don't do well married to another person with mental issues.
