Wife wont admit to affair and its driving me nuts!

[Morbo]

So had a few days away from W and girls.
Completely NC/dark from me and heard nothing from her either
til I texted her this morning(NY eve) telling me when to drop off the kids.Was busy the past few days, exercising, practicing, working and making plans for next year. My finances are getting better(credit cards coming down, paying back personal family loan) and I realize that was a huge part of our
marital difficulties, her inability to understand saving, too much credit cards etc
She never listened to me and just thought I was an idiot or a miser.
That comes directly from her mom who racked up huge debt in the family.
I started new savings accounts with the girls and made a big deal of bringing them to the counter where they deposited their new savings.
They're going to learn the value of saving, money from me. I've also set up
direct debits for savings for them and also sent W their info if she wants to contribute.

Anyway, she hung out for a while, talked about a couple of things they were doing and her plans for NY eve. I was nice but just polite and didnt ask any questions.

Then s**t got interesting.

W left and I worked in yard as girls were cycling and playing.
After an hour or two, youngest D came up to me crying and upset and asked when we would be divorced as she didnt want that and and wanted us all to be together again. I said, "I didnt know" and said the usual "Mom and dad love you and and nothing will change too much" etc
Then oldest D came up, was acting weird and said that they were out the previous day at the movies with mom and OM and then went for sushi and then on to yogurtology. Mom told her not to say anything. Oldest D is smart, she's heard me muttering obscenities about OM under my breath and knows whats going on.

Even though I know you guys here have told me that W is 100% having an affair, I still had doubts but I knew a line had been crossed now and so I called her. Tense conversation, "We're friends etc"LOL, and she kept steering it away from how she had nobody. "poor me", "you are a terrible person" and blah, blah. I kept it up and told her she was a liar and I didnt believe a word of it. After 15 mins of BS from her, I hung up. Then I talked to the girls again and found out they were with OM and W a few times and also at his house and his pool, all together. Oldest D said that although OM is ok guy they felt uncomfortable with the way OM and W look and interact with each other.. OM is seriously rich too and he's trying to buy their affections.
Called W again, but she's finding it harder and harder to deny anything although she's still blatantly lying, but I have everything I need to know and she hangs up after 5 minutes.

I have a 100% WW who has been cheating with boss/OM since at least nov 16. Not sure if PA started then. If she had told me then, it would have been hard to take but at least she could have been honest. People fall out of love, I get it.
But the way strung me along, baited me, gaslighted me caused untold misery to me and my girls for over a year. She completely tried to f**kin destroy me. EVERYTHING Sandi has said about the dark hearts of WW's is true.

So, I told family about it. She's now off the family whatsapp, my mom and dad dont want anything to do with her. She's lost me, she's lost my family. She's lost the respect of her daughters. Not sure if much will change and if OM is going to step more into the picture
but she knows the consequences of her actions and EVERYONE is going to know.

My only question is although I know W is reaping what she sowed, OM has been having a
great time with my W and probably both laughing at my expense. He also called me back in may 17 completely denying any wrongdoing, he was smooth as f**k and I of course believed him.
Soo, how do I make this piece of s**t suffer the consequences of his actions?

I really, REALLY want to go into their office where they both work and I want to announce what pieces of crap they both are, embarrass the f**k out of the both of them in front of all their co-workers to see. I wont be physical or anything, I KNOW I cant go down that road.
Is this a good idea? Should I just let this go?

Anyway, the sense of relief is amazing. I had a great new years last night with my daughters
and good friends.
2018 is going to be so much better :-)
