Is it ok if a guy I just started dating is talking about marriage?

I met him in person for 1 week then he has to go back to his country for work and his kids. He has one kid with his first baby mama and his second baby mama they have 3 kids together but never married any of them cuz he’s not ready and not so sure about the girl but he been with me only a month and talk about marrying with me while we just met on January? Or he tryna marry me to be his rebound or revenge on his baby mamas? Cuz if me and him work out together, I would want to marry too.
