I really like my friend

So there is this guy I knew like 4 years ago, we liked each other but neither of us were ready for a relationship back then so we stayed a close friends and we stopped talking during the quarantine but every now and then we check on each other. A few days ago he texted me and we start talking again like all the time just like the old days. And he keeps joking that he's in love with me and he'll marry me one day (in my community it's normal to marry someone u just met). So now idk if he really means it or its just a joke cuz I really really like him and I wanna be in a relationship w him but I'm afraid he doesn't want the same thing. So what should I do?
