Why is my friends with benefits mad I’m talking to another guy?

My friends with benefits male29 I’m female 23 is recently getting mad that I’m talking to another guy on social media.

When I’m not home he always asks me “ you on a date 🙄” but he never has asked me on a date himself?
We’ve been seeing each other for a few years now and I’m usually always available for him

Why does he act like this all of a sudden?
I don’t ask him any questions about other girls.
