Your Son is acting like this because he is in a lot of emotional pain. He is hurting and is lashing out at you, he is angry and blames you or is taking it out on you. I’m not sure if it is his Dad that is poisoning his opinion of you but until that pain is gone, nothing will get better.

I feel like you should sit down and just listen, no arguing or judgment. Just you and Him and say, “I love you, I’m sorry if I hurt you. Please talk to me about how you feel. I hate how our relationship is right now, I want it to change.” And then listen, if he scream that he hates you or something, then just ask “Why?” And then listen, if he believes something that is wrong then correct it, if you did something then apologize, give him a hug and comfort when needed.

Honestly, listening, and love can go a long way especially if he is an older child and wants to be independent. If he does not want to talk or pushes you then he is not ready for this and there is nothing you can do. Just pray and let him know you love him 🙂
