Building up Words

If I used one word
To describe you and me
I would say we're perfect
As perfect as can be

If I were to say two words
I feel when I'm in your arms
I feel so safe and secure
No one can do me harm

If I could say three words
To explain just how I feel
I would say I love you
My love for you is real

If I were to say four words
To let you know I care
I would say, I'm here for you
I promise to always be there

If I could tell you these things
If I were to let you know
I fear the truth would scare you off
And I'm not ready to let you go
