He may be afraid that if you make too many friends, he will leave him. He may be a very insecure person. You should communicate well with him and make fewer friends of the opposite sex.
He won't let you make friends. I don't think it's possible that he won't let you make friends of the same sex, but that he won't let you make friends of the opposite sex. After all, boys are very possessive. If boys see their girlfriends playing well with a heterosexual, they will probably go crazy. That's what my boyfriend does.
Before I was with him, I was a girl who loved making friends, and I had a good relationship with boys, so among my friends, male friends accounted for 6%.
He has always been very concerned about this. After I am with him, some male friends will still ask me out to play, and he will be very angry every time. However, if a female friend asks me out, he will not be angry or even happy, so that he can play games at home alone and won't be clamored by me to accompany me to watch various soap operas.
If your boyfriend and his sexual friends won't let you teach, it's probably too possessive. You should talk to him. If it doesn't make sense, break up. After all, you two may have different views. ?
