Grown as fuck and sacred

Soooooo basically my boyfriend is the v good to me he is sweet,caring and honest. I am 8 weeks pregnant and he is scared to tell his momma we literally live in our own place make our own money and go to school. Nothing we get is handed we work hard shit at least I do so it just bothers me that he feels like we gotta tip toe around his mom like if we were 16 mannn someone tell me how should I go about this
