Having crushes while being in a relationship (sort of) (edit: we're good now)

I'm seeing a guy I met here, while dating him I happen to find out that he is the kind of guy that appreciates women being pretty which isn't bad, that's great and all just rubs me off the wrong way considering were kind of together already. He's a fan of women celebrities and idols, but one person he follows stood out, she didn't look as famous, just a minor influencer from our country, just like any other person you'll pass by while on a walk or shopping. I asked him about it and and he immediately went on a speech about how she's weird and funny, how she finds him pretty ad said that was his "ideal woman". After that I've been drowning in thoughts about what he said, I was right there, we are dating, literally together already. He genuinely didn't notice he said anything wrong, I brought it up but he just says the same things again on how he just really likes her and how he finds her pretty and his type, then telling me he chose me. But I asked him would he hit on someone like her, if he was single yes but I was already here. I feel like he doesn't understand, that what he said felt really gut wrenching. He thinks he chose me but I wasn't a choice, I just happened to be there and was convenient, his choice was someone else. I'm aware that people have ideals and have crushes, but saying all that like it's not going to hurt me or fawning over someone else when I was there literally sitting next to him, really hurts. Edit: we had a really long talk, more like him trying to fix it as much as possible because I was really hurt, it's more like he didn't know what to do about it, when I did tell him he immediately understood and did it. He's really trying hard and I appreciate it, I'm just happy that he's patient and someone who won't give up even when I'm being difficult. And we pretty much had our first confession for each other as well, so I'm really happy. (edited)
