I want you to know I wrote this poem for you
I want you to know I am always thinking of you
I want you to know I think your perfect just being you
I want you to know I just want what's best for you
I want you to know I love you too
I want you to know you're always on my mind
I want you to know you're always in my dreams
I want you to know you're the owner of my heart
I want you to know you're my soul mate
I want you to know you're far more amazing than you think
I want you to know you're in every fiber of my being
I want you to know you're in everything I'm seeing
I want you to know how fast my heart beats for you
I want you to know how much promise I see in you
I want you to know how much I yearn for you
I want you to know how wonderful and beautiful you really are
I want you to know how much I love you
I want you to know how I know you love me too
I want you to know it's meant to be- you and me
I want you to know it's the best thing in my world- us- you
I want you to know it's love- it's us
I want you to know it's enchanting- all the love I see in your eyes
I want you to know it's forever and for always
I want you to know it's even after the end of our days
I want you to know my love for you is immeasurable
I want you to know my heart is filled with you
I want you to know my life is complete with you- my life is you
I want you to know my best days of my past are with you
I want you to know my best days of my present are with you
I want you to know my best days of my future are with you
I want you to know my dreams are nothing compared to you- my beautiful reality
I want you to know a lot, and there's a lot I have to say, there's a lot I don't know how to say
I want you to know I will do my best to let you know everything within my heart

But for now, saying "I love you" seems like the perfect place to start
