Divorce is a very serious matter. If you haven't already, we urge you to see a qualified counseling professional, as a couple or alone. Sometimes even a seemingly hopeless situation can improve with appropriate help. When a marriage cannot be saved, proper counseling can help improve the divorce process. A directory of religious counselors is available through Nefesh: The International Network of Orthodox Mental Health Professionals.
