In fact, sharing a room with a sloppy girl is really annoying. At this time, you'd better calm yourself down and not get angry. If you are angry, it will affect the relationship between the two of you, and it will be difficult to get along in the future. You should communicate with her well. Of course, don't mention her untidiness. After all, people have self-esteem. She is still a girl, so you have to give her some face. You should discuss it with her. Now that you two have become roommates, you'd better clean your room alone for one day. You can tell me what the cleaning standard is. If you have a good attitude, I'm sure she will do the same.

You can't stand it, you can choose to leave.

Some people are born sloppy, and nothing you can do can change them. If this time is really unacceptable, you can share it with her for a while and take the initiative to leave. Don't upset yourself because of her untidiness.
