Don't expect too much from your own affairs, that is, don't feel that you have to help you with everything. No one has this obligation. When you need help, it's no problem for you to think of your roommate at the first time, but you should communicate with each other well in advance and be mentally prepared. The other party doesn't have time to help you all the time. The other party has his own business. Don't expect too much, you won't be too disappointed. Naturally, I don't think roommates can be alienated. Don't create so much xenophobia for yourself, as if others are targeting you. In fact, it is just a manifestation of the other party's normal handling of things.
A proper study of hypocrisy means mutual business blowing, okay? It's simple. Some things can be said and some things can't be said. For example, the other person eats and waits for death to play games in the dormitory every day. Try not to say that you are just his roommate and you are not his parents. It is his own responsibility to stay in the dormitory and not go to class to play games. You have no obligation to remind each other. If the words are deep, it will make the other party feel unhappy and unnecessary. Then ask casually when you go out to buy things, do you need help, and so on. This won't take up too much of your time, but it will bring you unexpected surprises and help maintain the roommate relationship.
Getting along well with college roommates can reduce many troubles in life. Of course, we all want to get along like brothers and family, but you can't get your hopes up. You can't do it alone. Not everyone fits your personality and outlook. Some things are different and there is no way to change them.
