Irrevocable

I am 
Irrevocably
Irreversibly
In love with you

I must 
Undoubtedly
Indubitably
Do what my heart says to do

I hereby
Infinitely
Eternally
Vow my loyalty to you

I yearn
Constantly
Longingly
To do what lovers do

I pledge
Patience
Long-suffering
Til I can be with you

I promise
Devotion
Faithfulness
This is what I'll forever do
