You should not have to betray yourself to prove loyalty to someone else.

Any loyalty that requires you to act against your own values is not really loyalty, it is a test of compliance. Real closeness does not need you to become someone you do not respect in order to prove you are committed. When the price of staying is a piece of yourself, the arrangement has already gone wrong, whatever the relationship is called. That is worth noticing before the price rises.

Notice where you have gone quiet about something that matters to you in order to keep the peace. Ask what it has cost so far. Being honest is not disloyalty, and a relationship that cannot hold your honesty is telling you its limits.
