This is terrible advice…! Marriage takes lots of hard work, but the rewards are incredible. In marriage, there is a cycle of love and respect. When it starts spinning the wrong way (no-love/no-respect), you need to turn it around. It’s a choice.
Someone has been lying to you about the rewards, sweetheart. Put in all the hard work you want, but you’re an idiot if you think suffering through a miserable marriage will guarantee you any kind of eventual happiness.
