In principle, I don't agree with this approach. Forbidding people to talk about their marrital issues is a blessing (and tactic) for domestic violence.Why couldn't she keep the details of her marriage private, why did she need to tell the whole world?
Hiding the problems does not make the problems go away. We should encourage discussing marrital problems. Period. Pulling the face that everything is fine when it is not is bad for both the couple and and all the other couples, as it creates a culture of competing fake happiness.
Whether you should remain in a relationship if you constantly have issues to complain about - that's a whole different issue. But in that case at least, she did initiate a divorce, so it's not a case of "constantly complaining and nothing changing" either. In any case, to how many people she vented is not so very relevant to the crime at hand.
