Why he didn't text in between date?

We purely only chat when it comes to planning our upcoming date. Then both of us went silent. Even if we chat, its sooo rare. And most of the time, i initiate first, he do respond late, but good reply at least, not 1 word reply only..
I have talk with him, i'm so lazy to text him because he always reply late, to which he respond "because usually after class, i went to sleep or movie.. but if u text me 12am and above, i will always be free and reply to u immediately (but he know i sleep early)".. Not sure if thats a good excuses or no.. But yeah, apart from that, the fact that he rarely initiate any chat first except planning, i find it a bit weird..
