My man confronting my mom about my sexual abuse

I’m 20 now,the last time my mother ignored it happening was at 14 . And even went out with the man the next night . She’s allowed and looked over the sexual abuse from some of her boyfriends & I haven’t spoke to her about it yet .

My man feels he needs to talk to her about it for me .

Am I wrong for thinking it’s not his place ? Would you be comfortable with that?
