The light will be shed too late
In your 20’s, everybody’s got crapy relationships. At least, most do. Every woman is annoyed that her boyfriend doesn’t call more, or that he doesn’t plan more special nights for the two of them, and that he generally doesn’t prioritize her more. When you’re surrounded by relationships like this, it’s hard to see too many flaws in your own relationship. In fact, you might accept those dynamics as normal. But, if you get married young, as you get older, you’ll hear about your girlfriends dating progressively better men. Men who plan trips through Europe for them. Men who don’t mind doing housework. Men who prioritize them. Their relationships will move forward, and any flaws in your relationship will become painfully obvious.
