but I know im Charlie Brown and she is Lucy.
Late to this party, but I know the feeling. I told my XW that many times with her promises of change - yeah, she was Lucy telling me THIS TIME ITS DIFFERENT. And every time I landed on my back.
You can read the details in my profile, but short version: My xW was diagnosed Bipolar II, ADHD, depression, and one therapist thought she might be BPD (never offically diagnosed - XW bailed on that therapist). I think she is comorbid with BPD/NPD.
Multiple affairs over 7 years, blamed me for them. Did the smirk thing a lot of times. Accused me of being abusive because I yelled at her - after catching her with OMen. Basically everything you described, including the cutting - she told me she was going to kill herself and did that when I found sext messages on her phone and wouldn't give it back; I had to call the police at which point she told them it was stress release not suicide. The BPD/NPD are EXTREMELY manipulative and look normal to the outside world. And when you are upset about the manipulation and she's projecting normal, guess who looks like the insane one? It ain't her.
I will respectfully disagree with YOP - you really can't change a person with personality disorders. My first therapist who I saw after D-day#1 said when I told him about XW possibly being BPD, said in all his years (30+) he never saw anyone change. Go on websites about NPD/BPD (or here) and see how many success stories there are - very, very few.
I can tell you this: Now that you know about your WW cheating, you will be on the look out for more. And, the fact that your WW has been doing this for years means she won't stop. What that adds up to is a hell of a lot of pain, frustration and anger for you. It will literally start to drive YOU crazy.
It will boil over; in fact you already have. That's when you get hit with the abuse accusations. Not fun when the cops come and question you about being abusive for just asking who your WW is sexting (you've got the proof in your hand), BTDT (Which is why we say get the VAR).
As for your kids - they will suffer too. My XW started cheating when my oldest was 11. About a month after I found out, my DD started throwing fits - smashed my bedroom door with a metal chair. I grabbed her to stop her and hold her. Guess what? 6 years later my XW said I was beating my daughter on that day.
My middle daughter when she was 15 (two years ago) OD'd because she was so depressed and anxious over my XW's crazy behavior (we were separated, XW would go out partying and not come home).
My youngest didn't go to school for almost 3 years because of the anxiety and depression he suffered with dealing with XW - he found my middle daughter ODed and my XW OD'd 18 months earlier.
Now, are you going to have the same fate? I don't know. But I do know that BPD/NPD have a great tendency to spiral out of control. My ex started ~37 yo.
I know you want to help her (wait until you get the "if I had cancer would you abandon me?" speech from WW), but really you can't. In fact, any sign of help, compassion from you just screams "Sucker! He's buying my bullshit" to the PD.
I'm extremely loyal too. That's part of why we got sucked in to begin with, but you need to detach yourself from her as best you can (the 180).
I tell you all of this because this is what living with an unremorseful PD person is like. You know it. You've talked about all the abuse and disrespect you've already suffered. What will happen if you give in to her after knowing all about her affairs? She'll interpret that as a green light. In fact, she's already testing the boundaries with this retirement party. I can guarantee, in her mind, since there were no consequences (and you getting mad isn't a consequence to her - it is validation that she can control you and manipulate you), she can continue on.
You've been abused enough. Get out to protect your sanity and your kids.
