I started medical school with a 1 year old and a 3 year old. I then had a 3rd child in medical school. That all took a lot more time than dating.
In general, you want to think twice about dating someone in your class. If you are just compelled by undeniable attraction to a med school classmate, nothing I say will change your mind. But, breakups between 2 students in a class can be terrible. The learning environment is necessarily intimate at times - even the biggest medical school classes are still pretty small compared to most high school grades. Remember high school? Med school classes are sometimes the tenth the size of some of your high schools' class sizes. My advice is to go the law school library, or the gym.
