and I be alone?
The faintly Biblical language in which the Creature speaks is actually derived, and it would seem significantly so, from Milton. The vocabulary reflects the scene in which Adam names the various, already-mated species of animals, then asks God why he should himself be left in solitude. See Paradise Lost 8.389ff. and 8.594. In context, then, the Creature is telling Victor that he has broken the contract that God had made with Adam.
