Keep your so-called feelings in your heart and ferment slowly. Now it's time for you to calm down and study hard. You must first have a good future, a good prospect, and make the person you like feel dependent. Put yourself in others' shoes. If you are your teacher, a girl, older than you and have a stable job, then the first criterion for people to choose an object must be a stable and promising person who can take care of her. What do you have now? Generally, girls don't choose boys much younger than themselves. They need others to take care of them, worrying about their future and the opposition of their families. Therefore, you must be good enough to stand with her. Besides, you are still young, so-called like is not necessarily really like. When you slowly make yourself better and stronger, maybe you will have a clear picture and know what you really want. If you still like him, go for it. Now is not the time.
