How to stop being an overwhelming texter?

I love my best friend very much and we text pretty much all throughout the day but hes very busy at the moment and I feel like im overwhelming him. Hes said its fine but I want to make him comfortable. My worry is he doesnt really have any other friends and i dont want him to feel alone also I love talking to him so I need to find a way to differentiate whats important from stupid stuff but I’m not sure how lol. Any help is appreciated🤘
