Staying friends with an ex is a choice, not a maturity test.

Staying close after a breakup gets treated as evidence of how well you handled it, which puts the wrong thing on trial. Some people manage it easily, some find it quietly costs them for months, and neither one is the mature option. It depends on the two of you and on what is still being hoped for underneath. Choosing distance is not a failure of character.

If you are in this, ask what you actually want rather than how it looks. You are allowed to take space without declaring it permanent, and allowed to change your mind later. Decide for your own week, not for an audience.
