“the heart wants what it wants”.

Or maybe:

“the heart tricks you into thinking and believing that the one you want is something, or someone else besides what you already have, or what is readily available for you. but you choose, you want to succumb to the desire for the sake of pleasure that is actually equal to defying logic your mind has already said to you, over and over again. that forsaken joy brings you no security, no roof above your head, and yet you are prone to falling for it anyway, because it is addictive, it makes you feel alive, it makes you excited, it makes you going head over heels, but more often than not, it can easily break you, hurt you, and leave you deserted, with your heart broken into pieces. That is what the heart wants. That is what you get to follow your heart in its full glory and all these … fabricated happiness.”

Maybe?
