Are these signs of insecurity?

Indie

So I posed this picture I found on my Snapchat (not my text). I thought it was funny and relatable, nothing more. This morning my boyfriend sees it and freaks out saying why would I post this, I'm making it seem like I'm single, I suck at keeping the peace between us (he knew it was a random meme). I don't feel he should be upset. He's also gotten mad at me for adding a coworker on Instagram, posting selfies, and responding thanks when a guy wished me to get well soon. He doesn't think I should post cute pics because it's asking for attention and he doesn't think I should talk to any man even if it's just friendly. I don't freak out when he interacts with other women, that's life. There's a girl friend that he has that facetimed him (I said something just because I knew I could never get a FaceTime from a guy) his excuse was "her mom died and shes in pain". The girl was just in class saying what's up, she didn't call to talk about her mom at all. He claimes I can't have guy friends because he knows their intentions, but he doesn't say much about him having girl friends. Are these signs that he's insecure or am I being a bad girlfriend?
