how about

'You'll never know just how much, I miss you, you'll never know just how much I care, and if I tried, I still couldn't hide, my lov for you. You ought to know for haven't I told you so, a million or more times. you went away, and my heart went with you I breath your name in my every prayer. If there wre some other way to tell you I love you I'm sure I don't know how. You'll never know if you don't know now.

then there's

'I love you more than yesterday, but darling, not as much as tomorrow..'
