I am a single Mom with split/joint custody of my 12 year old boy. He has morphed into a person I barely recognize anymore. After a week and sometimes 2 with his dad (who attributes this change as "a phase" and "normal"), I see dramatic changes in his attitude and behavior. I allowed him to be on My Space, but with the condition that I would police his page at will. I did a history on my computer and found him doing searches for porn, lesbian porn, and other things I shudder to dwell upon. I went to his My Space and was equally disgusted with the language and the context of his conversations, especially with all the girls. I tried to bring the matter up gently with his dad, who just remarried last week. He was immediately defensive and wanted to have the details of my concerns over the phone. I believe that his dad uses non productive techniques and would rather punish than talk, so I said we would talk later. I know my son is growing up, but when I was faced with the opportunity to have a talk with him I froze. I need help
