Anger is really a secondary feeling. And I believe it mostly will not do you a lot of good. It usually is a reaction that stems from hurt, injustice or fear. So its important to try to pin point that root cause and if its real/valid learn to cope with it before you get angry. Errant, selfish, hostile spouses, often with psychological or character flaws can easily do or say things that ignite our anger. Often simply recalling what they have done could ignite our anger. I found myself getting furious at the beginning learning of the high-handed D filing, OM, disrespect in front of the kids, irresponsibility, etc. and these things are very hard to cope with, but becoming angry does not help our cause. They will say, "see, that's why I left ...".
