Separate or combine
I ask you one last time
It’s nearing the end of the relationship and one gives the other an ultimatum (presumably the male) on whether they should separate or finally become one with each other, something they have never accomplished.
“Last time” makes us think of whether they have been through aforementioned ultimatum before, an unresolved question that has to be answered.
