Courtship is about getting to know each other and developing a deep relationship before getting married whereas dating is mostly physical with no strings attached and no emotional intimacy.
What does a courtship look like?
During a courtship, a couple or group gets to know each other and decides if there will be an engagement. Courting includes activities such as dating where couples or groups go together for some activity (e.g., a meal or movie). Courting can also take place without personal contact, especially with modern technology.
