bullets not heading in the right direction, using Vector3.moveTowards

Hello all, I'm making a simplistic 2d space shooter and am having an issue when it comes to firing bullets into he correct direction, the way I have it currently is I have a child object called "firingDirection" attached to the player located far in front that will rotate to represent whatever direction the player is orientated in. After the bullet is instantiated in the start method I use Vector3.moveTowards to move the bullet to where the firingDirection game object was located when the start method runs. This works just fine when pressing play and only firing while rotating the player without moving.

The problem occurs after I have moved the player around a bit that it simply starts to fire in the wrong direction as shown in the picture below.

please help as I cannot figure this out I will post the bullet and player movement scripts below, thankyou!

 public class Bullets : MonoBehaviour
 {
     private Rigidbody2D rb;
     private GameObject firingDirection;
 
     public float speed;
     // Start is called before the first frame update
     void Start()
     {
         firingDirection = GameObject.FindGameObjectWithTag("firingDirection");
         rb = GetComponent<Rigidbody2D>();
         
         rb.velocity = Vector3.MoveTowards(transform.position, firingDirection.transform.position, speed * Time.deltaTime);
     }
 
     // Update is called once per frame
     void Update()
     {
         Invoke("Destroy", 3f);
     }
 
     void Destroy()
     {
         Destroy(gameObject);
     }
