I have a “friend” who I don’t want to be friends with anymore and I don’t know how to say it without hurting them

Ghost them, and make them no longer interested in being around you. Works wonders.

No question is ever dumb.
Just slowly spend less and less time with them, start declining their invitations to hang out (say you're busy or something), and hang out with others.
I don't really have experience with doing this but it has been done to me
