Red flag or nahh?

I’ve been seeing this guy M (30)
And we are interested in each other but he never goes out of his way to compliment me.
Not that I need it. I know how beautiful I already am, but is it wrong to want a guy to be obsessed with me? I compliment him as much as I can but I love it when a guy wants to publicly claim me and say what on their heart
Red flag or nahh?
