Break up help

So my bf and I have been together for almost 6 months and I’m trying to figure out how to let him down easy. Things went real fast and we said we loved each other really early on and then like we’re planning to move in together in the fall but I really am just ready to break things off I realized recently I really only love him as a friend and nothing more. Any tips? I’ve only broken up with someone once and it was a real long time ago.
