There are people who learn when they're in a relationship. For me, the learning often takes place in the aftermath when I'm alone. I learnt to play pool without you. Travelled to places without you. Read books without you. Watched films without you. Ran without you. It's like everything else is a substitute for the space you were supposed to fill, and now I'm more or less self-sufficient. I can't tell if that's a blessing or a curse.
