It still bothered Hermione to keep such a major secret from her husband. Even though she no longer believed he would run off with Ginny to start a new family, she couldn't shake the jealousy. Her own insecurities often came back at the most inopportune times to plague her. Perhaps there would never be a day when she wouldn't fear that her husband was only waiting for the moment that a fertile and willing witch was willing to give him what he desired to run away. It made even less sense considering how rocky the current state of their marriage was. There was absolutely no reason to believe that they would ever be able to reconcile their differences. He didn't trust her. She didn't want the same kind of future he did. If there was a better definition out there of an unhealthy relationship, she couldn't imagine it.
