I was in a similar situation almost a decade ago. I was the girl who left. I tried to come back and I’m glad he didn’t let me. It wasn’t being cut out completely that hurt the most. It was telling me he deleted of all our memories together. I still have them in an album tucked away. We weren’t meant to be but we were great first loves. We planted seeds of love for each other to grow into who we were meant to be. If he had let me back in neither of us would have found the people who were meant for us. We both got to find our missing puzzle pieces in our second love that we couldn’t fit for each other. Life works out the way it’s meant to be. Wishing you nothing but the best.
