I agree with Lillamy. Unless.... you're waking up angry, banging stuff around, calling him and ripping him up one side and down the other, hanging up, doing it all again... then MAYBE you should manage your emotions.
Anger is a sign that something is wrong: boundaries are being crossed or needs are going unmet, that something needs to be changed. I love this quote by Malcolm X:
"Usually when people are sad, they don't do anything. They just cry over their condition. But when they get angry, they bring about a change."
My sister brought it up in a discussion with my nephew recently. Then she told him probably the last thing he wanted to hear right then: sit down and figure out WHY you're angry and then see if you can figure out what you can do to change what's going on.
So, following my sister's line of thought. Rather than ruminating on the mess, can you take a moment to figure out exactly why you're angry and then start brainstorming what you can do?
