Please keep talking to him no matter what! I shut down once upon a time with my son. Then he started hiding everything .Like wagging school and going to internet cafes where he met more unsavory characters.(but he saw them as friends) (I saw them as parasites)

If you hang in there with him and hug him and kiss him and anything else that comforts him .....he will connect with you again. How old is he is it not too late? hope u get help here at pc. love from a fellow mum
