So much of my life had become trying to escape my ah and he wouldn't let me go!
So why would I want to spend another minute thinking about him or having anger about him? Anger connects me to him and assumes he is capable of doing anything differently.
Best thing I can do for myself is remember that I am as free from xah as my mind lets me be. He may have tried to trap me by starving me out of my apartment, preventing access to child support and healthcare...but if I am enjoying my life and not occupied with him in my brain - then I still am free as free can be.
I have learned to focus on the good things in my life. And I am not cynical or bitter. This allows me to love and at least try to trust, and to receive the love and trust of others.
So, no, you certainly don't have to stay angry. I certainly would recommend choosing a more positive path!
