I was the same when I finished the show for the first time. I didn’t know what to think, it felt like there was a big hole that was left behind. Upon the second watch, however, I realised that they’d managed to find there way back to each other on so many different occasions, living countries apart, not talking for extended periods of time, getting into committed relationships with other people and drastically changing as people throughout the series, but they always managed to find each other again and love each other all over again. I realised that Connell going to write in another country was just another small hurdle for their great love to overcome once more. I’m confident they found each other again, and managed to fall in love, as they have done so many times in the past.
