Hi Selene, i went through this awful painful experience of realising my son has abusive traits. My advice to you is to contact womens aid for supoort but treat him like you would any other abuser. If hes living with you, he abides by your rules. My ex was arrested leaving my son in his late teens at home with me. He got a job and felt he didnt have to contribute to household bills. His father paid for him to,move out, that was to try and punish and scare me leaving me alone but it was the best thing he could have ever done. He would come round on his fathers behalf and try to bully me. Luckily he moved out but living with him was hell. I keep my distance now. He knows where i am if he needs me but at least now he has some respect. I tried reasoning with him but in typical abuser style, he turned it round on me. In my house! Time to,help him fly the nest?
