Relationships are too important to learn how to face those issues at the last minute. You have to go through a few of them to know how to properly conduct one. You have to fail. You have to date a few terrible people. You have to be the asshole yourself sometimes. You have to learn how not to be the asshole. You have to spend tons of time together — so much time that sometimes you feel indistinguishable from each other and you find that both reassuring and disturbing. You have to have a vicious fight and know it’s not ending you and that you’re going to have to work to repair it and that the effort is worthwhile. These things take time.
I’ll wager that there is something about big transient cities that distorts everyone’s sense of time. You become convinced that you have time for everything you find challenging, that your ultimate horizon is infinite. This is only the beginning for you.
