Is this a red flag?

I'm dealing with an ex i used to date in highschool and back then i was like head over heels for him. It was that blind puppy love lol and i definitely didn't have any sense of self.

And well now I've grown up and I've experienced a lot of self love.

So when me and him get together we have this sense of familiarity and comfort, and he seems to be sure about me but i told him yesterday i have that comfort with him but i need to fall for him again.

And well i asked him why does he like me aside the fact that I'm pretty or that i make him feel all ooey gooey inside. Like what about me does he like. And he just says i just make him feel good and i care for him.

And there's nothing wrong with that but my thing is, I've changed a lot. And I've come to the realization that he never really knew who i was. I mean i didn't even know who i was back in highschool but i would cater to him because i was so caring and i loved him but i never got to really shine thru.

And now i feel like he doesn't even know me and he claims he does. But that's completely wrong. It's like the only reason he likes me is if it revolves around him, he can't tell me what qualities he likes about me.

And any chance he gets he wants to show me of but it just feels like I'm a trophy. like he likes the idea of me but not actually me.

I mean is it wrong for me to feel this way?
