I've been pretty hard on you, and want to say I am sorry, because I too did not really consider the amount of pain that would lead to the kind of behavior you've described.
I want to take another stab at this, though. Your statement below:
As a compassionate human being, would you be able to enjoy your holidays and see your H enjoy his holidays knowing full well that his actions turned a normal human being into a "sad and bitter person" while destroying his marriage? If you cannot do it then what makes you think she can?
Please don't tune me out when I say this: No one has the power to turn you into a sad and bitter person. That is a choice you are making. I know you don't believe that. I know that you want to believe that these people (your XWW and her AP) made you bitter. But can't you see how you are granting them power over you? And I'm telling you (along with multiple other people) that there is no one with that power.
I understand. Probably better than most. I want to share some of my background so you might believe that I'm not just telling you something I read or believe. It's not pretty. I'm going to be very, very explicit because it's important to me.
My mother is mentally ill. I grew up in a chaotic and abusive home where the threat of her suicide was a constant and real fear for me every single day. I can remember being in primary school, 7 or 8 years old, and riding the school bus home with a knot in my stomach, convinced that today would be the day I would find her dead and it would be my fault because I wasn't cute enough or funny enough or smart enough or "fill in the blank" enough. When I was in 3rd grade, my mother allowed her pedophile brother to move in our house in exchange for him providing free "child care." What he provided was a year of hell for me and my sister. I have a very clear memory of hiding under my bed as my uncle tried to pull me by my feet, and my mom coming to the room and yelling at me for waking her up.
He abused me in just about every way short of penetration. When I was 19, I lost my virginity to a friend of my brother's. I was almost comatose from the first time I ever drank alcohol. Consent was not possible. I was "awake" but had virtually no control of my body. I found out I was pregnant 3 weeks later. This guy then proceeded to tell horrific lies about me to escape responsibility. (This was before DNA testing and he claimed I'd been a willing participant in sex with multiple men and his commanding officer found that story "much more believable" than a 19 year old virgin.) I gave my child up for adoption at birth and spent the next 21 years trying to make all that pain go away. In the meantime, I got married to a sociopath who abused me mentally and cheated on me, leaving me with a newborn son who I raised alone until I met my current H, who also cheated on me multiple times.
I drank and drugged to try to make all that pain go away. I behaved abominably at times. I lost my nursing license for a year and ultimately almost went to prison before I finally did the work of recovery and got sober in 2008. I DESPISED the words "surrender" and "acceptance". And those words are thrown around a lot in recovery. I will never forget sitting in rehab and pouring out all of this stuff to my counselor. I told her I drank and drugged because of the pain of my past. She looked me dead in the eye and said, "HF, you don't have a past. Every bit of this stuff is in the present because you carry it around with you in a suitcase like some kind of treasure you don't want to put down. You will never get sober until you are willing to put this stuff in the past where it belongs."
Boom.
See, what happened to me as a child, and as a young woman, and as a wife was unacceptable. It was horrible and wrong and not one thing about it was fair. I was a victim and had no power in any of those situations. But every single time that I used that stuff as an excuse for drinking, using, treating people badly... every time I did that I was willingly placing myself back in that victim place. By using that pain as an excuse, I was ALLOWING THE ABUSE TO HAPPEN AGAIN. (emphasis intended. Not yelling.) What your XWW and AP did to you was inexcusable. Wrong. Horrible. But every time you act out in anger and pain you are inviting and reliving the betrayal. And this time, you are not innocent. It's your choice.
Back to those 2 dirty words. "Surrender." F*ck that. I don't surrender. I fight. I don't back down. I don't give up. That's how I felt. And then one day in 2008 I heard someone say, "Surrender is nothing more than joining the winning team." And that made sense to me. I was so damn tired of losing. Tired of hurting. I was ready to win. And one of the hardest things to grasp is that we win when we quit fighting. We win when we give up the idea that we can make the other person lose.
Which brings me to "acceptance." Oh, hell no! Acceptance? Doesn't that mean that I'm giving all those people who hurt me a pass? Isn't that saying that what they did was okay?
Not at all. Acceptance means I can say "This stuff happened to me and I am okay." It's giving up the delusion that I can make a better history. And the best part of acceptance is that when I accept that no one has the power to turn me into anything or make me do anything, I find my true power. If I'm a victim, then I'm powerless to do anything. But the truth is that I have the power to feel and do and be whatever I choose.
And so do you. You can choose to continue to be a sad and bitter person. Or you can choose to be victorious and content.
Your choice. Your power.
