I wrote lyrics for my song, but English is not my native language, so there may be some mistakes in word choice, or phrases, or style maybe. Can you check it and indicate my errors?

If I let you know how I love you,
If I let it flow now and show you
How I feel, then will you say 'Me too',
Won't you?

If I let you know how I miss you,
If I let it grow now and kiss you,
Will you go or will you kiss me too,
Won't you?

If I say I'm missing you so badly,
Everyday I love you more and more,
Will you stay or will you go away?
I must know it for sure.

If I let you know how I need you,
If I let it show now and lead you
To my heart, then will you need me too,
Won't you?
