What does this mean??

I’ve been seeing a guy for 3 months now. He’s 12 years older than me. I’m 28 and he’s 40.

He keeps saying sometimes he feels some type of way with that age gap. He started saying something like “ok imagine you’re 30 dating a 18 year old boy who just came out of high school and you have this career job already he doesn’t know wtf you’re talking about when you talk about your job”

Kinda felt offended and he said that he went through different life experiences than me. I told him it didn’t bother me but if it bothered him we should just cut it off. He didn’t say much and just kissed me
