My mother completely condoned this kind of behavior. Used it on us occasionally. "I'm mad at you, I don't want to talk to you right now. I do still love you and I'll come back when I've calmed down," was and is an acceptable thing for anyone in my family to say to anyone else.
Unfortunately we don't have control over all things, but we can control the way we think about the world. We are the creators of our own reality and perceptions can influence our reality. If we choose to perceive the world with a positive view, often even bad situations will seem less detrimental because of our hopeful outlook.
