Your boyfriend is a super narcissist, the identification is complete.
Prescription:
1. Sell the mirror
2. Secretly shave his hair
3. Turn a blind eye Close one eye and pretend you didn't see it
4. Communicate well and try to get him to change.
5. If none of the above methods work, it is recommended to change your boyfriend, because you have reached the point where you can't bear it, and he won't change.
PS: I am definitely not the man who likes to look in the mirror. Hehe, choose me. . . . . Hohoho··
