It seems like the end of a relationship, "every lie and say we'll be friends" And "another long sip...chapped lips" could be referring to a kiss maybe?

Rework the past, pretend we don't have a past might mean trying to forget that they ever dated, hoping to hold onto the friendship?

Compromised until our bodies siezed could be something like setting down some kind of rules to be friends, and the part about being "colder creatures" could refer to coldness of heart as they pretended not to have feelings for each other
