I can understand your fear, but try not to knock yourself for not being able to express how you felt. Remember that you are dealing with someone who could lash out at any moment. Try to look inside yourself for some inner strength, that's what my therapist told me to try to do. When you can build that up, it won't matter how he reacts because you'll know inside that all you did was voice how you felt in a calm way and that you have a right to do that without getting abused. I try to remind myself of that whenever I get yelled at, that it's not me doing it, it's him. Good luck and try to build some strength.
