Thanks a lot, Poli, for your corrections and suggestions!
I guess I need a rule, and it will be hard to get it.
I think I should consider the phrase
as much as apart from the other two structures:
as much ... as; so much... that. These last two ones are those I'm most interested in. Let's check some structures:
- I love you as much as you love that other guy.
- I love you so much that I would dance with a mouse all a whole night.
And now, trying to open a gap and filling it with some words:
- I gave you as much love as you brought indifference back to me.
- I felt so much in love that I'm flying without a pilot license.
Thanks a lot for your help!
