Anger problems in a relationship. How to deal/react?

THIS IS A REPOST FROM EARLIER TODAY.I NEED MORE THAN 3 ANSWERS. :) I believe my man may have an anger problem. I have noticed that he tends to get irritated and mad a lot easier than most people. It seams as if he has a very short fuse. I was just wondering what i can do to help him when he starts to get irritated? I have no idea what its like to feel the way he does. I understand this is something the individual should work on but im just wondering if there is something i can do to help and be a supportive girl friend? I would love some advice from someone who either has anger issues or from someone who is/has been in a relationship with somebody who has anger problems. Any helpful advice would be greatly appreciated. Thank you. :)
