Boyfriend struggles

So my boyfriend and I have been together for over a year now. Most of the year we are log distance as he has a job and I am still in school. One thing that really bothers me is that his social media doesn't really have me anywhere. I'm only in one Instagram post and I don't know if he does this purposesly but when I tag him in stuff sometimes the tags disappear but not always. I don't know why I let it bother me so much since all that matters really is us but it does especially when I see my friends and their boyfriends being lovey on social media! Am I the only one who has this problem?
