Should I be mad if my boyfriend is commenting on other girls posts?

Anonymous
I saw that my boyfriend liked this girls video on Instagram of her shaking her a** and commented "damn baby" with some emojis (this comment was posted this week), he has also liked about 50% of her other pictures/videos but hasn't commented. We are in a serious relationship (which he expressed that we are serious) and it does upset me especially because I would never disrespect him and our relationship like that and do such a thing. He told me from the very beginning of our relationship that he has always respected me, although clearly not.
Should I bring it up to him or am I overrreacting?
