Marriage

I’ve been dating this guy for half a year now and I still can’t over the one time he told me he would never marry me. We talked about it a couple days later and he apologize and didn’t say it to hurt me. He initially meant that he wasn’t planning on marriage any time soon which is perfectly fine with me but I never brought up the topic so I got really hurt by his comment which felt more like a statement (this was 3 months ago btw) and now we talked about marriage again and he was jokingly saying “don’t have any expectations” Idk how to feel. I’m still young so I’m not trying to get married any time right now but why would he keep saying that. Should I take it personally or move on from the situation???? It’s my first relationship and I’m 21, he is 27. I just don’t know how to handle what I’m feeling right now

UPDATE: I just want to say thank you to everyone who replied. I seriously didn’t know how to handle this situation. I talked with my bf and as it stands, he does not want to consider marriage if I don’t believe in god like he does. He is Christian and I am catholic. He said he would rather stay together with me for a long time versus getting married because he believes that our values will collide in the long run...Something in me says to stay in this relationship and ask again. Marriage isn’t important to me right now and I don’t want to get married until I am done with school. If he doesn’t want to consider marriage with me by then. I will not continue the relationship anymore. What do you think?
