In the first days, therapy focuses on calming the storm of emotion and on self-care: sleep, work, children and who around you can offer support. Big decisions are usually better made from a calmer place.
If both partners want to work on the relationship, couples therapy often follows stages: taking responsibility, answering questions honestly, understanding what was happening in the relationship, and rebuilding trust. Approaches such as emotionally focused couples therapy or the Gottman method are used here.
Individual therapy can help either partner too, whether to cope with the hurt or to understand motives and decide about the future. The therapist's aim is not judgement but clarity.
