What's wrong with him?

I (27f) agreed to attend a carnival with my coworker (23m), and during some activity I noticed by the way he glanced over at me that he was alittle interested. Afterwards he straight up started bringing up marriage (in general) and said that since he's moving states he'd like it if I'd move somewhere close. I assumed he was joking but the next day during some convo, he randomly asked if I could introduce him to my family and if I considered him marriage potential.
