He usually sends more than a sentence, sometimes paragraphs, pictures, links, vids, etc. He always keeps the conversation going, and changes the topic if the conversation starts to die down. He sometimes goes a day or two without replying, but he always texts back within 3 days as if he never "disappeared"
If I don't text him after we say bye to each other, he texts me again within 3 days.
there's no flirting, but yeah.

Sounds like he likes sending you stuff if he's bored or when the girl he likes doesn't text him back, then he uses you to make up for her lacking messages, play hard to get if he texts text him back the next day or so0
