try this tho
"Cannibalism as a metaphor for love is a topic that has recently been plaguing my mind, however, it is a concept that has been around for ages. It is used to describe a love that is obsessive and with craze, a love where one has a carnal desire to completely consume the otherness of their partner to fulfill a desire of closeness that normal physical exchanges cannot do. It is a yearning feeling to be completely whole with someone, as for them, love is not just a feeling of the heart fluttering for another, but an obese ache that rocks through a person’s whole body."
