Hold your breathe until you can't hold it any longer. That feeling of wanting to breath... that's how much I love you.
Look at the ocean, and its wide expanses that you can only see a small fraction of. The size of that ocean is as much as I love you.
Look up at the stars. There are trillions of them. There are far more than we will ever know about. The expanse of those stars doesn't equal how much I love you.
Now look me in the eye. My eyes have seen the beauty of the world. But nothing as beautiful as you. That is how much I love you.
I love you more than I love being able to breath, My love for you is larger than the water I need to survive. My love for you is so much more than anyone could ever understand. My love of your beauty is more than my love of any other thing to ever exist. And that, Is how much I love you.
