Advice?

Hey! So I’m 23 and I’m talking to this guy who I really realllyy like. We’ve hanged out twice and due to his busy cop schedule we haven’t been able to hang out but he’s told me he wants to see me again. He texts me everyday and even updates me about what he’s doing but sometimes I get annoyed when I see that sometimes he ignores me for 1-3 hours or doesn’t reply to me yet but posts on social media. I’m not sure if it’s normal to feel upset when the guy that your not even in a relationship with you takes long to answer? But it annoys me that I get upset over this because in my mind if a guy tells you that he likes you and is interested in you, why would you do that? If I liked a guy and was interested then I would make sure to reply fast to the person. Any thoughts? Should I even keep talking to him?
