My husband said that to me also, and I am jealous that he is so stable in his emotions, and I took it out on him. BlackPup has a good point-start small. When you see him in the morning smile and say good morning. Try to identify what is making you angry-you are hot, work was hard, you are hungry, house is messy, etc. Identify your emotion and what is causing it and decide if you can do anything about it, if you can't or choose not to, you have to try to let it go. I know that is easier said than done, but if you can just do it one or two times a day to start, it will get easier.
