1. You don’t have to DO things with each other.

You’re happy sitting in complete silence, if you’re just together. 

2. You focus on the cause of the problem.

If there’s a time when things aren’t right between you two, you choose to focus on the cause of the problem, and not who caused it. 

3. You’re happy with their successes.

You know that your success lies in their success and you’re genuinely happy for them.
