For the Love of My Life from the Man who adores you

Thank you for being the love of my life, the wonderful one I adore,
The person who shares all my dreams and desires,
My plans, my adventures, and more!
Thank you for being my very best friend,
my comforter when things g wrong,
the one who encourages, cheers me, believes in me,
changes my "weak" to my "strong".

Thank you for being my partner in life and for filling my heart
with such pride -- I feel like the happiest man
in the world with the woman I love by my side.

Happy Birthday
