Scenario: You are in a committed relationship and you sometimes suspect your significant other is smoking cigarettes. You are a former smoker with a huge dislike of smoking. When questioned, they repeatedly deny smoking. After several years, you finally learn the truth; they have been smoking at work - and lying about it - the entire time. Is this a valid reason to end the relationship?
Same scenario as question #1 - Would you be emotionally hurt and consider it a breach of trust when you learned of the deception?
