Am I wrong here or was he, reaction wise?

I feel my bf has been real shitty to me since I showed him an old pic I had taken of myself from like 4 years ago. It was me sitting on my bed in front of a mirror in a lounging angle, face cropped out, of me in my bra and underwear. I NEVER sent the pic to ANYONE but took it and kept for myself cause I thought I looked good in it, in which I also stated to him. I thought maybe he’d appreciate it since he said he loves my body and he was real quick to be like “oh were you a Snapchat slut back then?” Keep in mind I haven’t used Snapchat and deleted it like 3 years ago. I didn’t know what to say to that except was real quick to almost apologize and back peddle everything so he wouldn’t get jealous or mad? Fast forward two weeks later we are chilling in bed watching a movie and we’re talking about Instagram, and my insta has maybe 50 people, and it’s only people I know of family and friends. I was joking how compared to other people who have tons of followers how small my page is, and he said why not post the pics you showed me to get attention and gain followers? It was almost in a smug manner. I told him I don’t advertise myself like that…and he didn’t really even say anything after. But since then I feel he’s been crappy to me, to where I’m sorry I even showed him a pic I thought I looked good in and thought he’d appreciate? Like it was from 4 years ago, he didn’t exist in my life then… we’ve only been dating for 3 months now…thoughts??
