Making enemies push player back.

Hi all, I am a beginner in unity programming, and I'm currently making a parkour game. I want to make the enemies move towards player, and push him back. I have a c# script, which makes the enemies rotate to see the me, then move to me. It looks like this: using UnityEngine; using System.Collections;

 public class EnemyAI : MonoBehaviour {
     Transform target; //the enemy's target
     float moveSpeed = 3f; //move speed
     float rotationSpeed = 3f; //speed of turning
      
     Transform myTransform; //current transform data of this enemy
      
     void Awake()
     {
     myTransform = transform; //cache transform data for easy access/preformance
     }
      
     void Start()
     {
     target = GameObject.FindWithTag("Player").transform; //target the player
      
     }
      
     void Update () {
     //rotate to look at the player
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
     Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);
      
     //move towards the player
     myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
      
      
     }
 }

I got it from another thread on this forum, but the enemies just approach me and the rotate around me. So, I want to make them push me back. Is there a way to do this (I use the standard 1st person controller and the enemies are cubes, with box colliders. Also, I'd prefer c#, because i started programming with this language.
