Is this girl suspicious? Or I'm crazy?

Me and my bf have been together for 6 years for context. He went to a birthday party(I wasn't there) and there was this girl(I don't know her personally) and she was asking about me and if me and him are still together. And then she started bugging him like "why you don't want to dance are you scared of your girlfriend (me)?"

I find it kinda weird because she used to know him since middle school and they wrote hearts on Facebook and called him daddy. (when they were teens) 😂 I never took this seriously but she seems kind of suspicious to me especially that she broke up with her boyfriend not long ago.

I trust my boyfriend 100% and don't think anything about it. But she seems a bit desperate..

Also she and some other girl got drunk later and he and his friend took them home with a taxi.

Also after the bday party they went to a club and my boyfriend is not the type of guy to go there especially since covid we always made fun of people that can go into crowds like these and now he says that they insisted to go and that's why he went.. Then they didn't have enough money for their drinks and my bf and his friend covered the rest of their bill..

What do you think? Am I just crazy?
