Conflict is a healthy part of being in relationship. But you may need professional help to avoid it being destructive or overwhelming and transform it into a tool for deeper intimacy.
A healthy relationship allows each of you to be different without destroying it. Friends and family can be supportive in a crisis but inevitably they take sides and this can ultimately be unhelpful. In these times you may need the support of a professional and experienced person to help you work through these and other difficulties in a safe and confidential setting.
