Still Processing This

I just got out of a relationship that lasted three years and it’s been about a month now. The night we officially split, I was blindsided by the sudden emptiness and reached out to an old fling from college. We talked for hours on the phone, reminiscing, before she suggested we meet up. There was something so freeing in reconnecting with someone who knows you well but isn’t wrapped up in your current emotional state. It led us down paths that were both nostalgic and new, exploring each other’s bodies like it was our first time again. I’m not sure if I did this because I needed closure or simply craved comfort. Am I just being selfish or is this a natural part of healing? What do you think?
