What does it mean when a guy message you saying its okay to tell him if I dont wanna talk to him anymore?

I’ve been talking to a guy for a month now. Recently it felt like things are changing on his end with low energy and texts over the past 1.5 weeks after we had a problem. Usually I message him back everyday, but yesterday I didn’t message him at all because I was sad and tired of it. Surprisedly he even double message me yesterday. And this morning he sent me a sweet good morning and told me that it’s okay to tell him if I don’t wanna talk to him anymore.
