You are in the right place. Vent away. Edit nothing!
The simple fact is that this stuff sucks and it hurts. Further to that.... it does get better.
I am remarried and my X still pulls crap.... constanlty. It is the life she signed us all up for. Yet only she got what she wanted. Not me, nor my kids, nor our friends and families.
Simple fact: Most of our X's are nothing more nor less than selfish assholes.
Keeping this in mind should help limit your expectations and thereby limit disappointment. And as you move through this hell period, continue to do what you can to do something for you as an individual. Read, study, work out, flirt, or whatever will help you become a better person.
Because one day, "He" will fade significantly into the background and you will be there with you. When I arrived at this point, I really started to enjoy life again. And the me that I created (with lots of help) during hell-period was there to take part and enjoy the future that eventually shows up. Sorry... tht was a little convaluded but perhaps you get my point.
So be mad! This stuff hurts and there is no way around it. There is however a way THROUGH it. "When you are going through hell.... keep going" (Winston Churchill).
BTW.... Congrats on winning "Intriguing Thread Title of the Day". My unhealthy side is conspiring to out do this title and put something up so socially unacceptable that I will get banned. Ok... so maybe not.
But... you are among people who know so well where you are at. Dont look for justice in an unjust sitch. Just survive it and know that a brighter day is waiting. It is! Many of us are discovering that.
