The first unforgivable lie that keeps people unhappy in their marriage is the belief that marriage is easy. While the effort can be rewarding—just as fairy tale princesses and princes have always known—it’s anything but simple. Marriage requires work; although it’s valuable work, it’s still work nonetheless. One of the first things couples need to do is eliminate these misconceptions from their understanding of the commitment.
Here are the lies that keep people stuck in unhappy marriages:
1. ‘Your partner will fulfil every part of you’
“Sound familiar? It should. This is one of the unforgivable myths about marriage, endlessly reinforced by advertising, movies, and fabricated love stories. Another common deception is the belief that your partner exists solely to make you happy—always ready to soothe your sadness or heal your wounds. Yes, a loving partner may do some of these things, but ultimately, we are responsible for our own well‑being. A partner should be seen as a blessing, not a crutch.
Unfortunately, the more desperate we are for love, the more wounded or unfulfilled we feel, the easier it becomes to embrace the lie that happiness is our partner’s duty. That illusion can quietly destroy a marriage. And it’s not the only one. Other lies creep in too—the lies we tell ourselves, the lies born of shame, and the lies that mask betrayal so deeply that rebuilding trust feels impossible. Those, we’ll explore next.
2. ‘Your partner’s job is to keep you happy’
You are responsible for your own happiness—nobody else is. The best marriages are formed by two people who can truly understand themselves and each other. Remember fairy tales? Happy endings come after the beautiful princess has endured cruelty, deceit, and hard work. She remains strong in her goodness, bravery, and desire for love, while the prince has also worked to overcome obstacles. It’s similar to the aeroplane directive to put on your own oxygen mask first. There’s a reason that’s genuinely life-saving advice: If you can’t make yourself happy or love yourself first, you certainly won’t be able to provide that to the person you love.
3. ‘You’ll always have that in-love feeling’
The honeymoon phase always fades. Sure, you can reignite the spark, but that first rush of intoxication is limerence—not lasting love. Eventually, years in, it’s not grand gestures but small missteps that test you. A simple clash over how to load the dishwasher spirals: he insists you’re too critical, you argue that’s not what you meant, he grows angry, and you feel unheard. If unchecked, that tiny pinprick erupts into a volcano.
The problem is, we’ve been sold the lie that love should be flawless. So when reality shows up in the form of everyday conflict, it feels like betrayal. Here’s the spoiler: love is never perfect, and it never will be. What defines its strength is not the intensity of the early passion, but how you navigate the moments after the lust has cooled—the resilience, patience, and grace you bring when the spark dims.
