If you love me, don't love me for what I can do for you, how I make you feel, or how great you think I am. Love me in spite of my shortcomings, and in spite of my failures and imperfections. Love me in spite of the fact that I may hurt you deeply, or fall from the pedestal you have me on.
For that, I will give you everything, I will be loyal to the end, and I will strive to be a better man. I will lavish you with affection, I will always be honest, I will admit when I am wrong, and I will apologize sincerely when I say something or do something hurtful.
I cannot be perfect, and I do not expect perfection from you. I only ask that our love transcend the unpredictable, moody, and imperfect nature of our biology.
