am i allowed to feel this way?

am i allowed to not like that my boyfriend smokes weed all the time? i feel like he’s always high when he’s with me and it kind of offends me because it makes me feel like maybe i’m not enough for him, or like i’m not fun enough. he’s high practically all the time except for in school, but even occasionally during school. he’s a great person and i really really really like him but his drug habits are quite bothersome. however, i’m not sure i’m allowed to feel this way. am i allowed to say something? i don’t want to seem controlling but it makes me uncomfortable and makes me feel bad about myself. i also don’t like it because he has so much potential but i feel like he doesn’t actually live up to it because he’s high so often.
