Feresy
n.
the fear that your partner is changing in ways you don’t understand, even though they might be changes for the better, because it forces you to wonder whether your relationship needs a few careful nudges to fall back into balance, or perhaps is still as stable as ever, but involves a person who no longer exists.
Middle English fere, partner, companion + heresy, deviation from established practices or beliefs. Pronounced “fer-uh-see.”
