I think you should tell him exactly what you said here.
"I don't really care to see you again but when you send mixed signals it makes me think YOU want to see me again. I don't want to put in the effort with you. Hope you have good luck in the dating world!"
It is only a rough draft. When it comes to men you should tell them what you want them to know, not tell them something else and hope they do what you want! lol
