Welcome back ladies and gentlemen of the internet. You could be married for a decade, and still find out things in your partner you never knew could exist. Some people are good at masking their darkness, hiding in their own shadows, and keeping secrets from those around them. Once you've been married for awhile, your guard is down, and your trust is high, making it almost easier to lie candidly.
Just because it's easy to lie, doesn't excuse the behavior. Hiding things from your partner is a new level of indecent; it shows cowardice and petulance, that one can't own up to one's actions, and also can't cope with negative situations in a healthy, mature way. This brings us to the Reddit piece.
The story follows a woman and her husband. She thought they had a great relationship, until she came home one day to find him drinking whiskey, and looking through their wedding photos. He reveals everything about his affair, and in her blind rage she destroys his prized possessions. Fair? It's up for you to decide.
