Specifically, when your gf makes remarks around celebrities. Ex: Oscars last night and Leo DiCaprio flashes on screen.

Gf: ohhh hello!

She then ends up texting me this morning stating that she didn’t know Leo had a 22 year old gf. (She is 26)

Shit like this always pisses me off but I’m trying not to break frame. Do I address head on or go about it via a different approach? Your input is appreciated
