Separation is when you stop living together as a couple, even if you are still living in the same house. You do not need to get permission or your partner’s agreement. You have ‘split up’. Separation is a major step for everyone, and a time when you need help and information. Most people admit feeling the worst they have ever felt in their life. Grief, where you feel the loss of an important part of your life, may be the reason for this.
