How do you break up with a date?

So I recently went on a first date last week and was not into it at all. He has been texting me a lot about hanging out again and I know I'm going to have to send an uncomfortable text soon. I don't want to ghost because it's rude and not my style but I hate having to send these texts 😖

Do you guys keep it short and sweet or send a lengthly text? What's the best way to break up with someone you've barely dated?
