Meaning of “I'm sorry for blaming you for everything I couldn't do”
From Christina Aguilera - "Hurt":
> I'm sorry for blaming you for everything I couldn't do.
What does it mean?
> I'm sorry for blaming you and I'm also sorry for everything I couldn't do
or
> I'm sorry that I blamed you each time I couldn't do something
Or are both possible? (I'm not a native English speaker)
It's the latter. "I'm sorry that when I tried to do something and failed, I blamed you for it."
