If you want endless repetition (in your life), see a lot of different people. If you want infinite variety, stay with one.
What happens when you date is you run all your best moves and tell all your best stories — and in a way, that routine is a method for falling in love with yourself over and over.
You can’t do that with a longtime mate because he knows all that old material. With a long relationship, things die then are rekindled, and that shared process of rebirth deepens the love. It’s hard work, though, and a lot of people run at the first sign of trouble. You’re with this person, and suddenly you look like an asshole to them or they look like an asshole to you — it’s unpleasant, but if you can get through it you get closer and you learn a way of loving that’s different from the neurotic love enshrined in movies. It’s warmer and has more padding to it.
