wake me up before you go go

[Nefertiti]

Hi there.


"Left me sleeping in my bed
....
Don't leave me hanging on like a yo-yo."

1. to leave sb V-ing --- Is this a common usage?
Is it OK to say, "I'll leave you reading there in the den" or "I'll leave you crying in that room"?
Who's reading? You, right? Who's crying? You, right?

2. What does 'hang on like a yo-yo' mean? Is it a common usage?


"Cuddle up, baby, move in tight"

3. Does 'move in tight' mean moving closer to me? Is 'move in tight' a common usage?


Thanks in advance.

1 We do use it. You're right about who's crying/reading.
2 This is not a common usage; I have only heard it in the song. It means that the person is not having their feelings reciprocated.
3 It does.
