AIO my date compared me and my friends body

Hi, basically. I somehow attract the world’s worst men. I’ve been dating a guy for almost 3 months and he makes jokey comments to wind me up a lot. But I sent him a nice photo of me and my friends and he replied saying “not in a weird way, but how do you and your friends both have big b00bs”. I have been ignoring him and I messaged him saying that I didn’t want to not speak to him but he did upset me. He’s acting like it doesn’t matter at all but I think that’s such a weird comment to make? Like what does he gain from that.
