He called me sweetie pie?

hey all, I've been seeing this guy for seven months and he's said boo before and ik he likes me. I jokingly confronted him about something over text and he said "nuffin muffin lls". We were on the phone last night and he said "noooo sweetie pie" twice and "no honey" but he said it in a somewhat joking manner. My question is at this point do guys use terms of endearment like this when they're really into u and to assess what's ok to say?

He also recently started calling me a headass jokingly
