Waver vs vacillate
Vacillate describes going back and forth between options — the specific indecision of someone who cannot commit to a choice. Waver is broader: it describes both that kind of mental oscillation and the physical or emotional unsteadiness of someone whose conviction, voice, or resolve is faltering under pressure. You waver at a crucial moment; you vacillate over weeks. Waver can happen in a single instant of doubt; vacillate suggests a pattern of repeated oscillation.
