when do you stop being angry

As I have been in NC, Two weeks today! I have noticed I am angry at myself. Almost daily I remember something he did, and I think wow how did I not see it then.... So many times he physically hurt me, spit on me, argued some dumb thing that made no sense and then made it all my fault.... For three years I thought it was me, I thought, I love him so much, why can't I be better. He convinced me that I was crazy, that I needed help, lol good one, also that since we were together I was a better person. Puke. I am getting out of the so called FOG, I mean I have my days, but honestly NC has not been hard this time. I have broke in the past, but this is the longest I have ever gone. He is leaving in two weeks I think for a PTSD program in another state. I am counting on him being gone so I can breath again knowing he is far far away. I am angry. I want him to pay for what he did to me, ALL the money he took, the lies he told, hurting me, hurting my children, not being there for me when I had a c section, leaving me at home the day after my c section with a new born to see OW ( who was 18 years old). I am so angry I want him to pay for it all!!! I feel that my anger has fueled my healing a lot, but at some point I want to not give a crap.... When does that start?
