How do I respond to a guy who called me a "good girl" over a text?

It has a flirty vibe to it so say something flirty back if you like that person.
If before that intimacy conversation you say thank you daddy with wink, if normal conversation you say thank you.

Not sure what he means by "good girl".
@asker
Could you provide some context to the "good girl" comment so I might give some advice that would help? 😊
He just says it sometimes like you did a good job, you are a good girl.
Seems kind of insulting to me. Like talking down to someone.
We have known each other for a long time. He is 3 years older.
Are you into him? Try "Thank you daddy"
It’s easy you say thank you
