i have to wonder if "the internet is just too quick to say break up in relationship advice!!!" is actually correlation/causation getting backwards
e.g., it's not the internet being stuck in a rut, but more like wondering why there are so many sick people in an ER waiting room
if your relationship is to the point where people seek advice, there's usually a big problem that's popped up, and that problem often is big enough that the answer is "DTMFA and GTFO"
