Haven't been here in months, but he married her

I haven't been here in so, so long. I don't hav all the horrible obsessive thoughts anymore. I have been NC for 10 months. His choice, thank God, I wasn't strong enough to do it myself. I wish I could have, would have had the strength. But I didn't. He had me in grip for nearly three decades. He called the police twice when I tried to talk to him. I made a mistake....I outed him to his new supply. Told her EVERYTHING. Told her he is a pathological liar. Told her about all his affairs. Told he he is a narcissist. At the time, I WANTED her to walk away so I could have him back. But it didn't work. YOU NEVER "OUT"' A NARCISSIST. AND THE NEW SUPPLY WILL NEVER LISTEN TO THE TRUTH.
So.....he married her last week. He married her because he has been divorced twice. And he is desperate for everyone to think he is normal. I thank God he is out of my life after so many years. I thank God that I didn't leave my husband.....but I am angry. I hurt. I miss his being conned by the smoothest conman to ever live. It felt so wonderful. He was SO good at it.
I have spoken to wife 2 and to a former GF. He won't change....can't change....but, in the back of my mind I wonder. Is he going to be the perfect man now, at 54. I can imagine she is on cloud 9 now. Oh, he is so good at what he does.
