Boyfriend said I was 99% perfect?

My boyfriend said I was 99% perfect then went on to tell me that the missing 1% was that I’m not and older woman, or just in general, not older than him. This really made me overthink. I know it’s stupid but he knows I am insecure and he knows I overthink so I just hate when he mentions this stuff to me. I feel like I’m not good enough with how much he makes me feel like that. But he does say he loves me and we do have a somewhat healthy relationship. It’s just him sometimes making me feel like I’m not even his type?
