She comments about it at the end of #221 and put a big post on instagram about it. JD Roth is divorced too, but I don't think there's any real correlation between FIRE and divorce.
There actually could be, but maybe not the way that people think.
For a lot of couples, the driving force that pushes them to try and work through their marital difficulties is the financial impact that would come from divorce.
I can't tell you how many times I've seen someone seriously contemplate divorce, only to walk it back and commit to couples counseling once they figured out that they would have to give up their nice house and move to a basement apartment.
I've seen "he's the one who cheated, I shouldn't have to permanently lower my standard of living!" evolve into a will to forgive and move forward.
If someone can readily afford a divorce and either doesn't have to think about or isn't afraid of a lifestyle change, then they lack a HUGE source of pressure to try and make things work when things get really really hard.
An additional missing pressure is the fear of being judged. Most FIRE people, especially the public figures, are used to being judged harshly for their life choices.
I've seen a ton of intense fear around the scrutiny and embarrassment of divorce. Fear of judgement alone has motivated plenty of people to really knuckle down and try to ride through a marital rough patch.
That's two major pressures to stay together that are missing for wealthier FIRE folks. So, in a way, the freedom that FIRE provides may extend to a greater freedom to choose divorce.
