I’m please read I need an opinion

So lastnight me and my boyfriend were at a party.. we were just chillin in the kitchen kinda drunk and a big group of girls walked past and I watched my boyfriend look at each and everyone of those girls up and down... I was standing right there, so I said to him “I just saw you look all those girls up and down” and he just laughed.... so I stormed off and went home. Was he wrong? I don’t want nobody who is interested in everybody. He’s already cheated btw
