I want to travel with my classmates in the dormitory. Why doesn't my boyfriend agree anyway? He said that he was not only worried about my safety, but I couldn't tell him clearly.

Probably afraid that other boys will go with you. I don't believe you a little. If time permits, you can bring your boyfriend. But if he can't go, you must let him tell the reason. If he doesn't believe you, the problem is very serious. Don't let yourself be free because of him. Don't indulge him too much in this kind of thing, or he will definitely get worse in the future. But communicate more and speak calmly. Hope to adopt, thank you. Typing is tiring.
