I'm to far out of the game

A friend of mine recently asked me,
"So at what point did you ask Rob what you guys where, and how did you approach it?"

I answered but now I wonder if things are still the same all these years later. So ladies. What is the proper etiquette for "asking where things are going?" When do you move from just seeing each other to boyfriend girlfriend? Do people still even call it boyfriend girlfriend? Help me out here. I feel so clueless and unhip when I get asked shit like this.
