Problem gambling not only harms the gambler but can also harm their loved ones. Partners who live with someone with problem gambling may experience significant harm if their partner does not seek treatment. This study interviewed 15 people whose partner had a gambling problem but was not seeking help. The participants were constantly worried about and exhausted by their partner’s gambling. They also experienced a lot of relationship conflict and felt isolated from their partner. However, many of them kept the problem a secret from others due to stigma. Overall, there is a need to provide support programs for partners of people with a gambling problem.
