Why Can't I...

Why can't I believe you when you say you'll Keep a promise, Why can't I believe you when you say you'll be my friend forever... Why is it that when you say you will always be ther for me, you are missing, why is it that when I look into your eyes that you are not looking back... Why is it that when you say "I love you" I still feel like something is missing. Why can't you love me when I try so hard to love you in return.
