Whether on Reddit, TV or even real life, a common women's complaint is "the relationship isn't going anywhere" or " the relationship is not progressing".

What the hell does this mean? Where is a relationship supposed to go? Progress in what way? Is there any end to this? Is it like a shark that must perpetually swim or die?

Give us some particulars lasses.

EDIT: This was supposed to be a Question for Women, but the software interface felt otherwise, so, what the hey, everybody pile in. Let no man say I'm not inclusive.
