An estimated 47 million Americans identify as having an anxious attachment style, which can make being in relationships turbulent and emotionally taxing for them.

Relationships have always been essential to human survival. Our bodies and brains are programmed to seek out connection, whether familial, romantic, or platonic. And yet, these vital bonds are often at the root of our deepest suffering.

People in relationships with avoidants struggle with their lack of responsiveness and inability to tolerate real intimacy. Relationships between an avoidant and a partner of another attachment type are the largest group of unhappy relationships, and people who love their partners and who may have started families and had children with an avoidant will work very hard to try to make their relationships work better, out of love for their partner and children as well as their own happiness.

You’ve been playing games in your relationship for far too long and it’s about to cost you what you really you want: love. If you don’t pull it together and get a grip, you know you will be alone soon.

It’s not always easy to tell when you’re dealing with a narcissist. One day they draw you in with their confidence and charisma, the next they gaslight you, wreck your self-confidence, and leave you wondering, What could I have done differently? As Dr. Ramani Durvasula reveals in It's Not You, the answer is: absolutely nothing. Just as a tiger can’t change its stripes, a narcissist won’t stop manipulating and invalidating you. To heal in the aftermath of their abuse and protect yourself from future harm, you first have to accept that you are not to blame.

Being in a relationship without knowing how to share your feelings and receive your partner’s feelings in useful ways is like jumping into a pool without knowing how to swim. You can flail around all you want, but it’s not going to keep you afloat for very long—you need to be able to move in any direction at will. Like swimming, knowing how to share your feelings and respond to your partner's feelings will move your relationship in the direction you want: toward more intimacy, closeness, connection, and trust.

In You Are the One You’ve Been Waiting For, Dr. Richard Schwartz, the celebrated founder of Internal Family Systems (IFS) therapy, offers a new way—a path toward courageous love that replaces the striving, dependent, and disconnected approach to solving relationship challenges.

As polyamory continues to make its way into the mainstream, more and more people are exploring consensual nonmonogamy in the hope of experiencing more love, connection, sex, freedom and support.

It’s been three days with no call or text back...you can’t eat, sleep, or work.

There’s a common flaw that people who chase partners all have in common. Are you an anxious attacher? If you’re still holding your phone hoping they’ll reply then drop it now and pick up this book.

An affair: It can rob a couple of their relationship, their happiness, their very identity. And yet this extremely common human experience is so poorly understood.
