Social Media - Am I Trippin 🤔

So my bf & I have been together a year & a half now and I feel like he barely posts/acknowledges me on social media. He'll post his family, friends, parties, food & other stupid shit but hardly ever anything about me or our relationship. I've said something about it before & his reply was "I have a disdain for social media". Now it's not that I'm insecure or anything it's just that I feel that his followers/friends may not know he's in a relationship due to lack of evidence on his social media (Snapchat) . My birthday was last weekend & it was literally the worst birthday to date; he knew I was feeling down bcus of this. I watched his snap story to see what he was up to that day & to see what he wrote about me and to my surprise he didn't write shit about me for my birthday. Naturally I was mad/sad & I confronted him about it and his reply was "oh, I was gonna post you before I went to bed" like WTF ??? In what world is it okay to acknowledge your SO's Birthday literally minutes before it's over ??? Am I wrong for feeling like this ?
