By Ellen Wachtel - I used to believe that if a couple was getting along and behaving in a loving way to one another, hurtful and even cruel words would naturally fade into the background. But I’ve frequently seen couples in which hurt spouses may forgive their partner for the harsh words spoken in anger, but nonetheless remain haunted by some biting comment that continues to sting long after the argument is over.

By Kate Cohen-Posey - We live in an age in which using toxic verbiage against others has almost become the norm. Here's how we can help clients deal with these kinds of situations in the moment.

Sex therapist Suzanne Iasenza talks about a three-part process that helps couples free themselves from the rigid narratives about sex that keep them from exploring what really brings them pleasure.

By Esther Perel - It’s long been the conventional wisdom among couples therapists that if couples fix the emotional issues in their relationship, their sexual lives will improve. But good intimacy doesn’t guarantee good sex.

By David Treadway - How do any of us therapists know what’s good enough in the unfolding of people’s lives? I know I practice an often intuitive craft, not an exact and predictable science. The truth is that all too often, like most practitioners, I can never be quite sure how much difference my bit part plays in the unfolding drama of clients' lives.

By Steven Stosny - Intimate betrayal strikes at the core of our capacity to trust and love, violating the fundamental expectation that gives us the courage to connect deeply—the belief that the person we love won’t intentionally hurt us. This requires therapists to reach a balance between validating their clients’ pain and empowering them to improve their lives.

By Terry Real - It's disrespectful to clients not to let them in on the truth about what we witness regularly in our offices as they play out their relationships in front of us: the ways they deal with their partners are often self-centered, unfeeling, and counterproductive. I believe that in order to teach our clients how to be authentic and connected, we must be real with them ourselves.

By Michele Scheinkman - Underlying the perceived magnitude of an affair is an idealized view of marriage as the "shelter" in our lives, with a primary function of providing emotional security and attunement. I've found it perplexing that, although we live in an ostensibly liberal and sexually permissive society, therapists typically have one-track minds regarding how to approach infidelity.

Of course, sexual affairs are red flags for infidelity, but there are common elements that make any outside relationship an infidelity. Sex therapist Tammy Nelson explains what they are and how to spot them.

By Silvina Irwin - It’s my first session with Jeff and Miranda. “Honestly, I don’t know why I’m here,” Miranda spits out. “He's cheated on me since we started dating 25 years ago." Can I avoid doing further damage to their precarious relationship? Do I tell Miranda to run for the hills? What if Miranda takes a leap of faith and decides to trust Jeff once more—and he betrays her yet again?
