Should my boyfriend be mad that I’m now friends with all guys?

I’ve always been jealous of my boyfriend’s social life. He’s friends with both guys and girls and would go to parties without me. I felt insecure that I never had a life outside of him and felt like a big loser compared to him. I wanted to show him that I can be social and have a separate friend group too. I joined a gaming club at our college because I love video games and I was the only girl there. At first I felt awkward that I was the only female, but the guys enjoyed my company and said they always wanted a girl to be apart of their group. I started hanging out with them when my boyfriend was with his friends and I started playing video games and going to the gym with my new guy friends. I even started drinking and smoking with them. One day when my boyfriend was at a party with his friends he posted a picture with them on his snap story. I was with my guy friends that night and we were smoking weed. I had enough so I took a photo with them and posted it on my snap story with a caption that said. “Smoking weed with the boys.” My boyfriend saw it and got mad at me. He said I shouldn’t be hanging out with all guys. I don’t get why he’s not happy for me that I now have my own social life away from him. Was I wrong for doing that? I finally have my own friend group and he’s not even happy for me.
