Welcome back internet enthusiasts. If there's one thing that's true, it's that people can change. Anyone who says differently obviously has a story behind it. But I can even say for myself, I've seen myself change in so many ways that I wouldn't even be able to recognize the person I used to be. Knowing this can be helpful while in marriages, or dealing with interpersonal relationships. How someone is now, or the state of things now, does not necessarily mean anything for the future. People do grow up; they learn, they mature, and they can change in ways unimaginable.
In this Reddit thread, it's about high school sweethearts that didn't last. Together for twenty years, and their marriage was cut short due to certain differences. In their mid-20s, they decided they didn't want children, but he changed, and decided he wanted them. Years after their divorce, he finds out she's married and pregnant. In anger, he wants to meet and talk with her about their marriage.
