Can you transalte this male language?

So i work with my boyfriend
I left earlier yesterday, had a dantist
So today
He told me
"You can't leave work early... you gotta stay to the end"
I was like"wtf are you talking about"
He said he nearly had a fight because other coworker is a dickhead and started to say nonsense stuff that made him angry
So... what did he mean by you can't leave
Did he mean i calm him or what
Can you transalte this male language?
