BF won’t post me on Instagram

My bf and I have been together almost 6 years and has never posted a photo of us on Instagram. He doesn’t post pictures on Instagram but will post a story once in a blue. He tried to say he doesn’t post but he does follow people, comment, like send memes and engage with people on Instagram. He uses it everyday.

What do you guys think? I feel like he should at least have one photo of us on there to at least show that he is in a relationship 🙄 I have multiple photos of us on my Instagram.
