It's one sided, he does not love you, does not cuddle, he seeks heat that has nothing to do with love or bonding but has to do with basic needs.Love is a very broad term that seems to fit many different things. In one definition, love is simply the protective instinct within us. In another, it's a connection between two parties of knowing/understanding. Personally, I feel that love is not really an emotion, but a level of bonding. Wheatley knows/remembers my scent, and is comfortable being around me. He likes my warmth, and feels safe. He's fallen asleep on me before. Though there is nothing clearly indicative of a bond, I think it's unfair to claim that they cannot bond to their handlers.
Now you can chose other words to replace needs or instincks but it's still does not mean there is love, protection or bonding on the snake's end, only on yours.
Again you are attributing human emotions to a snake that is lacking the frontal part of his brain where emotions such as love resides.
