They really like shopping and usually buy things that they don't need. Even though they don't have enough money, they buy everything they want. There isn't a specific answer. Some people go shopping when they are sad, worried, upset or lonely and they want to feel better. They use this activity as a way to forget their problems.
Shopaholics say that they feel more important and better after they buy something.
They also tend to have this addiction when they feel guilty. For example, a husband might buy very expensive presents for his family to try to make up for his lack of love for them. Men really like shopping because they feel they have power and control. They get whatever they want. Also, men usually buy big items while women spend their money on clothes, cosmetics, decorations for their houses, or things for family.
