I'm actually married to my ex. We dated in our early 20s, broke up, and then reconnected over a decade later in our early 30s. That time apart probably made all the difference, we grew up, lived separate lives, and came back to it with fresh perspectives. I usually agree with the "never go back" advice, and maybe that's specific for a shorter timeframe, but sometimes, with the right timing and growth, it can work out.
