It depends on your family dynamics. Are you the type of couple who really talk about your marriage problems and work together to solve it? Like in our case, I talk to my spouse about it - ask for the reason it happened again and his plans to avoid it in the future. I also ask him of there's anything I can do to help him to prevent ot from happening again. I usually do this after I have calmed down so we can talk objectively.
If by "repeated offense" you mean cheating, and I assume you do, I would seek out help from a marriage counselor.
You should talked ur husband.
