In A Star is Born,
Jake Jack, whose wife wants him to be in her performance, was met by Rez:
Rez: Just by staying married to you, she looks like a joke. It's embarrassing. Let's be honest, we both know it's only a matter of time before that's pushed aside again for the real thing. And when that happens, I don't want her anywhere near you.
With again, it means that the marriage has been forgotten or ignored before in the past.
I saw the movie, but I can’t remember where Jack’s marriage was ignored.
What past is Rez referring to?
