I'm crying right now, knowing my ex wasted my life. She sucked all the happiness out of me, then blamed me for our problems. And is dating before I can even move out.

I feel so betrayed, so used. She's a textbook narcissist, and I missed all the signs. I have enabled her for 20+ years. And now she's lying to me about dating before I move out, saying she's going "on errands". My older daughter was trying to text her and she wasn't responding so she tracked her and she was in a random rural area. so clearly on a date, and likely fucking the guy given the venue. Yet she still expects me to help her and be the slave I've been my entire marriage. Nope, she can handle all herself, I'm done helping, I'm done being anything but her adversary. And if she brings anything up, I'll just say "you know why".
