Ex-bf

so i broke up with my bf last night because i just wasnt feeling it anymore. he didnt do anything wrong but i just lost feelings. anyway he started texting my best friend and he told her that he loved me. which he didnt tell me yet. he also told her a plan he had to "win me back". and it was that he was going to get all of our friends to hold signs about how he loves me and to get back together with him. and they would all make a circle around me and he would come in and ask. so i told her that i dont like him and that he doesnt deserve to be dating someone who doesnt like him. and i told him that i would say no and how he deserves better but he said he was going to do it anyway. what im asking is what should i say to let him down easy what that time comes?
