How do you change your behavior in marriage with a Narcissist to end his dependence as supply?

1. Set boundaries. This is the most important step. You need to let your spouse know what behaviors are no longer acceptable. For example, you may decide that you will no longer tolerate being yelled at or belittled. When your spouse crosses a boundary, you need to enforce it by walking away or taking other action.

2. Be assertive. This means standing up for yourself and your rights, even when it is difficult. You don't have to be aggressive, but you do need to be firm. When your spouse tries to control or manipulate you, you need to be able to say no.

3. Build a support system. This is essential for your emotional well-being. Find friends, family members, or a therapist who can listen to you and support you. Having a support system will help you to cope with the challenges of living with a narcissist.

4. Take care of yourself. This includes both your physical and mental health. Make sure you are eating healthy, getting enough sleep, and exercising regularly. Spend time doing things that you enjoy and relax you. It is important to take care of yourself so that you can be strong for yourself and your children.

5. Be prepared to leave. If your spouse's behavior does not improve, you may need to consider leaving the marriage. This is a difficult decision, but it may be the best thing for you and your children.
