Because nobody is pulling. For two people who learned early that closeness comes with a bill, finding a partner who never sends one feels like finally being understood. No one counts your reply times. No one calls a meeting about the relationship. Weekends apart need no defending.
Both of you read the absence of demands as compatibility, and partly you are right. Mutual respect for independence is a real strength, and plenty of secure couples would envy it. The problem is what the easiness is made of. It is not the peace of two people who can handle closeness. It is the quiet of two people who have agreed, without ever saying it, not to ask each other for any.
