Romantic 1st lines...and deadly 2nd ones

Rhymes with the most romantic first line... but the least romantic second line.

I thought that I could love no other
Until, that is, I met your brother.

Roses are red, violets are blue, sugar is sweet, and so are you.
But the roses are wilting, the violets are dead, the sugar bowl's empty and so is your head.

Oh loving beauty you float with grace
If only you could hide your face

Kind, intelligent, loving and hot;
This describes everything you are not

I want to feel your sweet embrace
But don't take that paper bag off of your face

I love your smile, your face, and your eyes -
Damn, I'm good at telling lies!

My darling, my lover, my beautiful wife:
Marrying you screwed up my life

I see your face when I am dreaming.
That's why I always wake up screaming

My love, you take my breath away.
What have you stepped in to smell this way

My feelings for you no words can tell,
Except for maybe "go to hell"
