If someone needs you to prove your love every single day, they don’t want a partner. They want a performance.

Reassurance given on demand stops meaning much fairly quickly. When affection has to be demonstrated daily, the demonstration becomes the relationship, and your attention goes into passing tests rather than into being together. The need underneath is usually old fear rather than anything you caused. That does not make it your job to satisfy on a schedule.

Notice whether reassurance ever settles the question or only resets the timer. Say that you are willing to be steady and not willing to be auditioned. Then let consistency make the case instead of daily proof.
