In the early days of your relationship with your young stepson, it was your responsibility as the adult to get on with him. You should have done everything within your power ...and more ...to ensure that you built a strong and respectful relationship together. That being said, this is an impossible question to answer in the here and now, as you do not say what is happening in your life together. My only thought would be for you and your stepson to go somewhere together for a weekend, on your own ..maybe camping and just walk and talk, about everything or nothing. This would be a starting point and maybe progress could be made if you both try to be honest and not just 'right.'
