I never watched Batman Beyond ( A lot of the old Cartoons are on Amazon Prime so I will be catching up over the next couple of weeks), but in it was Barbara not a long term ex of Bruces?

Unfortunately, yes. But it's barely mentioned and all instances of it can be easily glanced over. Killing Joke is where it got super creepy and downright insulting to both characters.
