My son aged 15 has been in a bit of trouble lately, drugs, shoplifting, detentions at school. My husband and I have recently divorced but are still living together for now (long story - house on the market) and I have a new boyfriend who I think I tried to introduce the kids to too early. My son's recent behaviour has meant that I have struggled to trust him. This morning I saw something that made me suspicious of him and when I challenged him after school he went completely mad. He was furious with me for not trusting him and he smashed a chair up in his bedroom and threw things down the stairs. We had a real shouting match and he just doesn't seem to understand that I feel the need to police him at the moment due to his past behaviour. He's very hormonal and also very upset about the divorce and the new partner - any advice on how to make life a bit easier for all of us?
