Girls, Am I overreacting girls?

I’ve been dating a guy for 11 months. 11 months. We have had sex like alll the time and speak all the time. I told him about my close friends during this time. I shown him pictures of my close friends. He then went and followed one of them on instagram and liked her photos? I know this because obviously she told me. So I told him I feel disrespected and he said I’m overreacting? An I seriously over reacting? Is that not disrespectful. Liking photos is a thing you do to gain someone’s attention?
