Write a letter to him. Put in it all your feelings (good and bad). Let him know how you feel about him and the way he treats you. Open your heart and just let the words flow freely onto the paper. When you are done, throw it away.
Do NOT give it to him. You will be surprised at at how you will feel afterward. You get to let your feelings out without doing any damage. I used to do it. It made me feel so much better.
Try it, it can't hurt anything. Just make sure you throw it away so no one sees it.
