Is it normal to be jealous if your spouse has a friendship with someone of the same gender as you? Is it possible for a man and woman to be friends? If you trust someone, does this mean that you never get jealous? Can you be too jealous? (The Torah laws of yichud provide a protective fence around relationships.)
