I don't know why anyone (even including lawyers) thinks this belongs in a public record or in divorce proceedings. Just say "irreconcilable differences" and that should be enough for the judge. Move on with your lives separately if you can't move on together, but don't air your dirty laundry in public. Out of respect for the love I hope they used to have, they should be respectful of each other even during divorce.
Note: I have no opinion on Joni Ernst.
I don’t know if you’ve ever been to “divorce court” but judges ask all kinds of questions that really are none of their business. They insist they do this in order to “protect” the party born w/o penis.
