What is the colloquial term for the stage a couple goes through once the initial excitement of the relationship begins to wear off, minor irritations occur, and they see a need to start adjusting to each other's differences to maintain harmony?
I have it narrowed down to these two, but I'm not sure if they are correct:
They’ve reached the stage where they are rubbing each other’s corners off.
They've reached the stage where they’re filing down each other’s rough edges.
Do either of these ring a bell? (I mean grammatically speaking, I'm
not prying)!
