As long as your girlfriend doesn't care about your education, there will be no problem. As a boyfriend, even if she is older than you, you should love her, care for her, care for her in all kinds of small details of life and give her a sense of security.

If we are talking about marriage, we should not always indulge in love, but should encourage each other, help each other and work hard for our future.

If you are not in a hurry to get married, and you don't think there is any result, then you should treat her well, don't always focus on her, you should focus on your future development.

May your career and love have a good harvest! I hope I can help you.
