Hello I am a single parent of 2 boys.My youngest just turned 16 and I am at my limit with him. It started when he was 13 years old. He use to be my baby boy and almost over night he is like a stranger to me. He doesn't drink or do drugs but dose smoke cigarettes. I pride myself on honest and finding myself at a battle with my son over it. He lies to me about everything. I punish him and he tries to twist the story he first gave me. Then he gets to where he doesn't care about what I take off of him and won't do any of his chores and says to me ...well Im getting punished anyways so. The harder I push the more he kicks. It's a battle everytime ..all the time..I try therapy and when he gets punished for something like lying to me he just refuses to go to therapy I believe its cause he knows it upsets me so as a punishment for me. He does whatever he wants and wants to take no responsibility. What can I do?
