H e has split from his girlfriend and I'm to blame in his eyes. H e has kicked a door of its hinges, taken my phone, threatened the girlfriends dad, smashed up her phone. I vs suspended the phone accounts so mine might also be smashed now. I've locked him out to give him time to cook down and avoid the backlash. I'm frightened what he might do. He's very I mature, he struggles to manage and regulate his emotions generally and he is impulsive. His girlfriend told me he's using a lot of drugs. I suspected that anyway. His dad doesn't really want to acknowledge his existance. I'm on my own. No support. I don't know what to do for the best. Please help.
