Social Media postings

Anyone ever been with someone who gets upset and counts how many times you post them on social media. Even though they rarely post you? I rarely post on my fb and my boyfriend is upset because I didn’t post him. So I post him on Instagram, I don’t always post on instagram. I rarely post, I’m just there for memes. I post him on insta about once every other month. Posts nothing of me. I don’t get upset cause he doesn’t post on social media either, just shares things. So now he feels a way even after I STILL posted him. I apologized and everything. What am I doing wrong here?
