Why Do Relationships Really Fall Apart?

In this episode of Begin Again, couples therapist and Netflix’s Blue Therapy relationship expert Karen Doherty opens up about what really causes couples to drift apart, lose intimacy, and stop feeling connected. With over 25 years of experience working with couples, Karen explains why so many relationships do not end because of one dramatic event, but because of a slow, quiet disconnect that grows over time.

Karen explores the hidden patterns that can damage a relationship: unresolved triggers, contempt, poor timing, emotional shutdown, infidelity, loss of trust, and the everyday resentments that slowly wear away at love. She explains why couples often fight about the surface issue, like the dishwasher, sex, money, or tone of voice, when the real problem is usually feeling unseen, rejected, criticised, or misunderstood.

This conversation also dives deep into intimacy, and why it is about far more than sex. Karen breaks down the different forms of intimacy, from emotional and physical closeness to humour, curiosity, micro-connections, and the small daily gestures that help couples feel chosen again. She also shares why scheduled intimacy, honest conversations, and understanding each other’s triggers can be powerful tools for rebuilding connection.

At its core, this is a conversation about love, repair, and what it really takes to keep a relationship alive. Whether you are in crisis, quietly drifting, rebuilding trust, or simply trying to understand your partner better, Karen offers a hopeful and practical reminder: relationships need care, attention, and intention but there is almost always a way back to connection.

Sometimes, the choice to begin again is the clearest sign that love is still there.
