Dating

Hello, my name is Mary. I recently have a crush on one of the boys in my class. He is cute, kind, and good at sports. Of course, he is also popular among the girls. Interestingly, he also has a crush on me! We started to date in secret because we would get in serious trouble if our parents or classmates found out that we are dating. One day, my mom found out accidentally that I am dating him and she was very worried. But our dating is not as serious as she thinks and she should not be that concerned. To us, dating simply means texting a lot and having fun when we are together. I also think that I can learn how to understand another person, how to respect someone, and how to build a relationship by dating him. My mom says that dating at a young age will have a negative impact on my studies and my future. She also warned me that if I do not break up with him, she would take away my cell phone. What should I do?
