Raycasting + setActive()

I'm basically trying to make an outline of an object by having a duplicate of the object as a child of the object. When the cursor is over the original objectthan the duplicate will then appear (duplicate will be a bit behind the original and a tad bigger with a solid -colour material). I'm having trouble making this work. As of this moment i have...

     private RaycastHit hit;
     private Ray ray;
 
     public string otherObjectName;
     
     void Update()
     {
         ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         bool didRayHit = Physics.Raycast(ray, out hit);
 
         if(didRayHit == true && hit.collider.name == otherObjectName)
         {
             gameObject.SetActive(true);
             Debug.Log ("in");
         }
 
         else
         {
             gameObject.SetActive(false);
             Debug.Log ("out");
         }
     }

When i hover over the original object nothing changes. Not quite sure what i'm doing wrong and any help here will be appreciated.

Just something i noticed:

• The logs: At the beginning (when i'm not hovering over the original) it'll print "out", which is fine. When i hover over the original it'll print "in", which again is fine. However, when i hover out of the original it'll still be stuck on "in" and will not change again.

• If i change the SetActive() in the if statement to SetActive(false) and then have SetActive(true) in the else it'll work fine (in reverse) but only once (when i hover over the original the duplicate will disappear but won't appear again even if i hover over the original)
