Because of what happened, one of the two parties may feel neglected. As you expected, this will lead to many other problems until the relationship finally ends. Even if you think you can balance school, extracurricular activities and interpersonal relationships, others may not. To tell the truth, it is unfair to give them such expectations and pressure. The key to success in any school year is to be strong at the beginning. This means that you must get into work, attend classes on time, do your homework on time (even in advance), and prepare for the exam that the professor decides to give you in the first week.
Taking notes in class will help you a lot in the future. This doesn't mean that you should only concentrate on your study. What I really want to say is that once you get into this habit, you will find many other things less stressful. Not only that, it is easier to know how much free time you have and whether you feel enough to maintain a relationship. The last one may be obvious, but if you fall in love at first sight, then date him, and then things move quickly, then the chance of breaking up is about 50%.
It's one thing if you already know this person, but if you only know one person, you should take the time to get to know them. By the way, just going out for a few weeks is not enough. Many times, love belongs to the category of "when you feel love, you will know". You will know whether your date or interested person is right for you, so don't worry. Slowly, make sure that he/she is the one you really want and the one you are destined to be with. So I think the reason why you shouldn't date at the beginning of college is that the first semester of college is a transitional period.
