are my feelings valid?

i’ve been with my boyfriend (17) for 2 and a half years. i love him with everything in my heart but i feel like it’s one sided and he doesn’t respect me. for example he used to post me all the time and so did i but he stopped at one point and just never posted me again. i post him all the time, you can find highlights of us and him and he’s even on my second account. i asked him about it and he said it’s because he just doesn’t want his family to know we’re together because then i won’t be able to come over anymore but he has a private account as well and has posted literally everyone else in his life, even those he’s only talked to for a couple months AND a girl he used to have feelings for and i’m no where to be found on any of his profiles. it makes me feel bad and he knows that and he said he’d make a highlight of us but that was 7 months ago. i also am always trying to get to know him more. i’ll ask him questions about himself but he never asks me anything about myself, except for the rare occasions of the “hbu” responses.
