should i text him or not? (ldr bf) i'll answer yours too!?

Yesterday around six i sent him a message, he saw it half an hour later but never replied. It was probably cause he had classes till 9pm. So i waited to see if he'd reply or wtv.

Finally he texted me saying that he was going to sleep now, goodnight and stuff. I replied as usual. I woke up at 2am and saw that he was online only minutes before.

The next morning he texted me, i have to tell you the truth, haha, i didnt sleep last night. It turns out he was planning to but he couldnt sleep.

And now i want to tell him that i accidentally missed class lol, but idk if i should cause im hurt tht he never replied my question at 6 yesterday. What should i do?
