Need 'How to' on exposure,,,, and balls to do it

[Optimust]

With advice from bro, friends, W best friend, IC, nurse that took my blood pressure and had a WH, and the Dr that gave me the anxiety pills,,,
I’ve come to the conclusion that I need to stop this even if it causes a D.
I am deserving a better M than what I’m in now, and there is a very very slim chance that it will get better if I don’t expose the EA/PA.

“. I want to be in a committed, open, and honest relationship. This will not happen as long as you are in an affair with OM, weather it be emotional or physical, it disrespects me, the vows we took, and our family. This marriage doesn’t have room for 3 people. This is about choices, your choices not mine. You need to figure this out soon. If you choose me and the life we have here with our daughters, you must end all contact with him, forever, and we will fix our issues together. If you are undecided or choose him then you will need to find other living arrangements, and I will need to let everyone know.”

This seems a bit wordy, but says what I need to get across, I think. Depending on the answer, I would plan on setting boundaries to include a NC letter, transparency, and IC and MC for both of us.

She will either deny affair, try to minimize to ‘just a friend’, or admit it. If she denies, I’m thinking:
“You were with him at the mall yesterday, and with him at the mall by his house yesterday, and also met him multiple other times, you spent the night at his home multiple times, and are in constant contact with him, and trying to hide all of this from everyone including me, this is THE definition of an emotional affair which may or may not have evolved into a physical affair”

Timing, I work 12 hours today, and until 6 on Saturday, I’m off on Sunday and I think we are going to church that morning, and off Monday, but then I work 8am to 8pm for 10 straight days. She has to be at house for kids during those 10 days, so I was thinking this would happen Monday night, so she couldn’t run off to him for advice, and hopefully think it through a bit without his or my influence.

Please critique above plan, and add any advice you have.

ps - Isn't there aletter on here somewhere addressed to OM boss saying like," I've always respected your company, and was shocked to find out one of your employees,,,,," - I might want to use it
