Boys? Advice? Help??

So I randomly started talking to this guy from my old HS. I was a little nerd, and he was a jock. One day he followed me on Twitter, I dmed him some random weather report after he was wishing for a snow day, and we started a convo, eventually exchanged numbers. Have been texting every (ish) day for around a month. He is really cute and sweet, but it seems like he is a bad texter... orrr not into it anymore? Can’t tell. He will reply, and in the beginning the conversation flowed and was with more detail. Now it is kind of mundane, and there are hours and hours in between. He was on spring break a few weeks ago, and now I am. I think he may be busy, but how would I know if i’m annoying him? I had said before that I was sorry if I was annoying, and he said I wasn’t and stuff. I’m super self conscious about being a nuisance or bother. How would I know if I am? I attached some of our messages. Gimme advice! ❤️
