Second, find a way to isolate you. If the misunderstanding can be eliminated, it will be eliminated. Otherwise, if you embellish it, it will have a bad influence on you. Not only is it frightening, but things that hurt college students have never happened. If you think there is something wrong with your concept, let's just say that you are love rat or too selfish (just assuming, no offense). I hope you can correct it, otherwise you will not adapt to stepping into society in the future.
Third, if you just want to form a small group, and all three people are overbearing people, you can apply for a dormitory change or rent a house by yourself. Stay away from those who are more powerful. Anyway, people are doomed to go a long way, and no one can recognize anyone outside the school gate.
Can I say that my roommate has built more than n groups behind my back? Although there are not only three of them, the three of them joined others to form a league. In short, I am not in these groups.
Why is this happening? Because I can't play with them. They are in the same class and I am in another class. I can't stand going with them, whether it's living habits or study habits. Slowly, I alienated them and they alienated me. I know about building a group, but I can accept it. But sometimes I feel isolated.
In this case, it must be not only their problems, but also their own reasons. As the saying goes, if they don't cooperate, it's convenient for the three of them to build a group alone, so don't bother you.
In a university dormitory, a good relationship between four people is of course the best. If they can't do it, at least they should maintain a superficial peace. Some things, see through, don't say anything, everyone is fine. For this kind of relationship, don't treat them as friends, don't help everything, the less you help, the better, the best not to help, the best not to disturb them, just living in the same space.
