I am not a medical student, and now I am exposed to medicine. I have a medical friend, male, who has been admitted to graduate school and broke up with his girlfriend last year. What I want to say is that medical students are really tired, very tired, and the degree of fatigue can refer to the above three answers. I don't know if your description is objective, or if you just described your feelings from your own standpoint. As far as you are concerned, my friend who studied medicine was not like your current boyfriend before we broke up, but it may really be caused by the postgraduate entrance examination. He will take pains to buy gifts for his girlfriend, he will want to contact her family, and he will visit her. I think that if a person has feelings for you or doesn't care about you, he can feel it himself. For example, although he is very busy with his studies, he still sends a few short messages every day to ask if you care about you and tell you whether he is good or not in his study and life. If he doesn't, it doesn't mean he has no feelings for you and doesn't like you. It only shows that the power of reality makes you dispensable.

The above is just my personal opinion, for your reference. I think you should not think too much, let nature take its course, and do what you should do, whether it is study or life, study more, read more, exercise more, make more friends, love yourself, treat others sincerely, be kind and simple, and strive to live a more wonderful life without him (not to mention the overflow of private life), because there is a saying that if you are in full bloom, you will be happy.

Bless you!
