What is the process for a survivor to deal with anger?

It seems to me that anger is the mainstay of my husband's personality. Sometimes it simmers in a quiet hum in the background of our lives - and sometimes it bursts free and he strikes out against unimportant people, things or situations. The anger has stopped being directed at me, but it is still there. Still there. I can feel it every day.

Any survivors have success at working through this kind of thing?
