reference to monobehaviour in static script,declaring a static class/script in a monobehaviour

Hello friends I have looked far and wide and I cannot locate anything on the internet to help me with this

Basically, I have two scripts: One is a monobehaviour and one is a static script my static script needs to get things from the monobehaviour. i know monobehaviours can reference other monobehaviours by getting the script component from an attached object but you cant attach static scripts to objects so i keep getting "object reference not set to an instance of an object" but i dont. know how to like declare a monobehaviour in a static script and i am losing my mind

heres a sample of the monobehavior

 public class dexReader : MonoBehaviour
 {
     //misc variables not important
     
     public int GetAttack(string characterName)
     {
         //code that returns an int attack value 
     }

and heres the static one

 public class Character
         {
         //lotsof variables only showing relevant ones
             protected int rarity;
             protected string charName;
             public int attack;
             public GameObject dataHandler; 
 //this the obj script is attached to
             private dexReader dexReader;    
 //this the script (normally declared at start like "dexReader = dataHandler.GetComponent<dexReader>();" but cannot do that because theres no!! start!! function in static!!
             
             //init new char
             public Character(int rar, string nam)
             {
                 rarity = rar;
                 charName = nam;
                 
                 attack = dexReader.GetAttack(nam);
                 
             }
         }
 

annnnd heres the line thats making the null reference whatever stupid error (in another monobehaviour script)

 Character testingguy = new Character(1, "Test Starter Character");

ANYWAYS any help would be appreciated I literally cannot figure out what to do and its driving me insane
