How to check if game object is destroyed?

My OnTriggerExit2D is being called even though the collider has been destroyed. I'd like a way to check whether the colliding object has been destroyed or not. Is there any way to do this short of adding a bool to my colliding object?

Code:

         private void OnTriggerEnter2D(Collider2D collision)
         {
             Destroy(collision.gameObject);
         }
     
     
         private void OnTriggerExit2D(Collider2D collision)
         {
             // collision.gameObject != null -- Doesn't work
             // collision.gameObject.activeSelf -- Doesn't work
             Debug.Log("OnTriggerExit2D is being triggered on a destroy");
         }
