boyfriend compliments another girl sexually....😡😡😡

But my bf joined this fb page where it's like a troll pages and these girls post booty pics and shit and he commented " I'd do unspeakable things to you." And I got mad bc I saw it. And asked him does he like complimenting other girls sexually and not feel bad about me? And he said it was just a compliment for someone else to feel good about themselves. I am so upset. Sorry, like am I overreacting or I got all rights to be mad!!? 😡😡😡
