Why did he say this to me?

I recently reconnected with an old flame and we plan to meet soon. He told me he doesn’t want to be my friends with benefits or casual etc. However, he went on a rant about how the dating scene is just casual/people dating several others at once. And he said he doesn’t want to his waste his time etc. Why is he telling me this? I felt a little awkward after because I didn’t know exactly how to take it. Does he mean he only wants us to date eachother or something?
