Red flag behavior?

The guy I’m seeing keeps treating me like his girlfriend, good morning & goodnight texts, texts me saying he’s thinking about me, has nicknames for me, talks about the future etc.. I have made it very clear I just want to be friends with benefits here and there with a nice cuddle after. I just got out of a three year relationship. I almost called the whole thing off early on because it got so intense so quickly, then I said I wouldn’t if we’d keep it casual. Is this red flag behavior? What should I do? I worry he is testing my boundaries
