Should I just leave him alone?

So, I've been seeing this guy for about a month. When we first met I was in full on crush mode. We've been on three dates but I feel like it won't go anywhere. I'm 19 and he's 28, and I don't care about the age difference. He's made some remarks about how sad it is for older guys to date younger girls. It honestly offended me and made me feel disappointed that he wouldn't see past my age. Even though keep in mind, he's the one that keeps pursuing me. Should I just leave him be and forget about him?
