Why is that...?

Why is that every minute of every hour of every day, my thoughts are filled with you?
Why is that when you're away I keep hearing your voice calling my name?
Why is that everywhere I look, I see your face as clear as day in my mind filling my heart with longing for you?
Why is that I fall deeper and deeper in love with you when I know I can't have you?
Why is that when I know the consequences of falling for you and heartbreak I will go through, I still want to be with you?
But everytime I try to stop myself those simple words that you keep telling me would ring loudly in my head.

"You are beautiful."

Those three simple words have gotten me spellbound to you.
Why is that...?
