Getting immunizations does not mean you have the disease. You get them for preventative care. Just as counseling does not mean you are getting divorced. It means you care enough to prevent it.
As much as we hate to take our children to get immunizations we do it because we love and care for them and don’t want them to suffer from any disease, expecially those that are preventative. Take your marriage that serious. Check in with a coach or a counselor to keep things on track.
