i don’t think my boyfriends mom likes me

i’ve been with him for half a year and i noticed his mom doesn’t want him with me. She’ll tell him to go out to his friends and not to be with me, she will make cheeky remarks towards me. i don’t know what i done, i haven’t really met her properly so maybe that’s why ? but he’s almost 20 why does he listen to her ? Today i heard her say on facetime that he needs to stop making excuses to see me so she obviously told him not to see me anymore

i was thinking about texting her but she would probably hate me even more
