There's another post concerning a similar question, but after reading through it, I'm still not sure about the meaning of the sentence I encountered:
The calendar was blank, as it had been every day this month, except for the third Thursday, where she had scribbled, Civic Association Meeting. Molly sighed, remembering a time when every day had held a different list of assignments and chores, schedules for Erik, and important meetings for Cole. Eight years ago she had needed a calm, almost boring, lifestyle to save her sanity. Now, she wondered if she hadn’t let it go on that way for too long.
Was Molly regretting that she had let herself live "that way" for too long, or was she missing being "that way" when she found she had nothing to do?
