The falsity of love is quite self-evident, as well. It makes no sense why I should feel emotional attachment towards my parents and brother. Proximity isn't valid, because I can be in close proximity to people I hate, such as co-workers and sibling rivalries. Utility isn't valid, because a child arguably gets more material benefit from prior investments into healthcare, education, and food by the government or other organisations. Gratitude isn't valid, because a mother may choose to birth a child due to less-than-selfless reasons (social pressures and legal restrictions against abortion, the social incentive of being a mother, utility of having a child as an investment/security, a sense of duty to sustain a lineage, et cetera). Overall, it seems that love is entirely false, nothing more than an anachronistic remnant of our ancestral past, where social bonds were created out of necessity to survive in a turbid environment.
