To complete you I broke into pieces
They warned me, but I ignored
Or: I was warned, but I didn't pay attention
I realized that yours is false
Or: I realized that your love is fake
It was the drop that overflowed the glass
This is an expression similar to the English: It was the straw that broke the camel's back
Don't tell me that you're sorry
That seems sincere, but I know you well and I know that you lie
I congratulate you, how well you act
