Next, ask yourself, "What triggered this reaction?" Do your arms shake with rage and frustration every time your husband has to stay at work late and finish a project with his female co-worker? Do you experience fear and panic every time your wife leaves for a working weekend out of town? Write down your feelings. Talk about them with a close friend, your spouse, or a trained counselor. Note exactly how you feel next time you're overcome by jealousy. This isn't as easy as it sounds.
