need boyfriend advice !!

okay soooo my boyfriend and i have been dating for 8 months. i’m a junior and he’s a senior, he’s almost 18. in the summer we saw each other probably every other day. now that school and football has started we see each other maybe once a week if i’m lucky. on days where he doesn’t have games/practice i ask if we can hangout and he says yes for the whole week. then either the night before orrrr the morning of he tells me he has to do something or his mom says no. so i’ve started wondering if maybe his mom just doesn’t like me?? i haven’t done anything to her but now she never wants him to do anything with me. i don’t know if she is actually telling him no or he just doesn’t wanna hangout... idk but it’s really hurting my feelings and everytime i tell him he just doesn’t understand and i don’t want to feel like i have to chase him to keep him you know? so what are yalls thoughts? sorry this was long ):
