Citing Obama is ridiculous, but she is grasping at straws to get you to see that she sees NO OTHER ALTERNATIVE that she can live with, and so the kids must be ok with it.
You know better. This is not going to be easy on the kids at all, and they're not going to grow up and be President just because Obama did. You must treat your kids like the individuals they are, and get them the help they need at the time they need it. Maybe they will be fine, maybe not, but you will do all you can, right?
Coparenting classes would be a great start if she's interested. If you didn't end up getting divorced what would be the harm in having had some education in coparenting? Or read some well regarded books on helping children in divorce situations. Taking actions like that won't push your W toward divorce if she was already headed in that direction but might give her an inkling that you're making the best of things and taking her seriously.
