Stop Walking on Eggshells for Partners: What to Do When Your Partner Has Borderline or Narcissistic Personality Disorder

In a relationship with someone who has BPD or NPD? You deserve clarity, safety, and the power to choose what’s right for you.

If your romantic partner, spouse, husband, wife, boyfriend, or girlfriend struggles with borderline personality disorder (BPD) or narcissistic personality disorder (NPD), you may feel trapped in a cycle of gaslighting, emotional abuse, blame, and high-conflict arguments. You may question your reality, feel trauma bonded, or struggle with codependency and fear of separation. Whether you are married, dating, considering divorce, or navigating coparenting in a high-conflict custody battle, the emotional toll can be overwhelming.

It is not your fault.

From the author of Stop Walking on Eggshells, BPD and narcissism expert Randi Kreger offers a practical survival guide for romantic partners living with, loving, or leaving someone with BPD or NPD. Grounded in research and informed by DBT (dialectical behavior therapy) principles developed by Marsha Linehan, this guide provides clear tools to help you protect yourself, set boundaries, and make confident decisions about your relationship.

In this book, you’ll learn how to:

• Recognize patterns of gaslighting, verbal abuse, psychological abuse, and covert manipulation
• Understand trauma bonding, codependent dynamics, and high-conflict relationship cycles
• Set strong boundaries and defuse explosive arguments safely
• Evaluate whether to stay, separate, divorce, or pursue counseling
• Navigate coparenting, custody battles, and post-separation conflict
• Rebuild self-trust, emotional resilience, and long-term recovery

Whether you choose to work on your marriage, seek separation, or move toward divorce, this compassionate, no-nonsense guide helps you step out of confusion and into clarity. You’ll gain the understanding, coping skills, and confidence needed to protect your well-being and create a more peaceful future.

You are not stuck. There is a way forward―and you can move toward safety, strength, and a healthier life.
