Is there anything that I(F18) could do when he(M18) is scared to commit?

Background: I am currently in my last year of high school. L and I have been close friends since Junior year. We were genuinely just friends until last October, when he started developing feelings for me.

L confessed to me last Christmas, and after days of thinking, I said yes to him. However, he then replied to me saying that he thinks we are better off as friends because we would have the potential to be LDRs (long distance relationship) after high school. I was really sad but I still agreed to be friends instead.

In those days after his confession, I actually also thought about the possibility of LDR, but I still said yes to his confession for I believe that we can make it. However, when he said he will be backing out, I am a little disappointed that he is being irresponsible and does not trust that I (or we) can overcome those possible barriers.

Fast forward to January, our conversations were still kind of flirty and I did not want to stay in a love with no commitment, so I asked him if he is still pursuing me because I am confused with our current situation. He said he is sorry for his feelings went back even after saying that he is moving on, and he said he is trying his best now to move on.

I could feel that he really likes me, but is doubting because of those potential barriers. I DO NOT WANT HIM TO MOVE ON but is there anything I can do?
