We must also realise why we get angry.
I actually get furious with H when he says that, because he thinks that my anger comes from within me and has nothing to do with what he says or does. Of course I will get furious when he spends all weekend with his headphones in, listening to music and making jokes with FB friends. Of course I will get mad when he tells me what to do all the time, but stonewalls if I make a comment. I get mad at his lack of ability to acknowledge his own mistakes, to say sorry, pay a compliment...
On the other hand, he's got a point. Just one. Our reactions always belong to us, even if they are justified. Our anger isn't their anger. We feel angry because we want them to behave in a different way. And somewhere, deep down inside, is our own angry child. We are subconsciously replaying something from our own past, too.
We need to detach, GAL, and set boundaries (different to those we set when they were in replay). We need work on our own inner calm (I'm not so good at that), and be prepared to let them be who they are, or let them go, without being angry. If we are angry, it's because we still want something from them, something they are (for now) unable to give. So if we tell them to go in a moment of anger, it's because we are not done yet. See what I mean? I've also got to that point.
It's a hard path, this reconciliation business.
