So, so sorry you are seemingly trapped in an abusive situation. I wish I had wise words but I know nothing about the laws surrounding divorce. The stress must be immense and yet still you hold the higher ground by not sinking to his level. You should be proud of yourself. Can your Mum come over to support you while your hubby is at work. Sounds to me like you need all the support you can get right now.
