I say you give me his address so I can go beat his !@#. In all seriousness I am very sorry to hear what happened to you. I have to small daughters and one of my worst fears is something like this happening to them. I applaude your courage to come here and post. I wish I had better advice except you need to talk with the doc, get of the pills, and out of that realtionship immediately. I can't imagine someone doing what they did knowing your previous history. Your fiance should be someone you look to to protect you from the terrors in life, not be a facilitator of them. This is just my opinion, but i call them how I see them.
