If you got back together with a significant other, would you keep the date you got together the same as the original or would you start it over?

I'd actually celebrate both... the first because it's the date you started going out together.

The second as a symbol of how far you've come as a couple. You faced whatever and broke up, but you were able to talk it through and see that you still loved each other enough to work through the rough times.

In my experience, it's important for us to take stock of how we've grown as a person within a relationship - and that's an example of that. Usually, when we celebrate anniversaries, we only tend to focus more on a dinner and doing something nice together rather than making an effort to remember and appreciate how much we have grown individually and as a couple.
