"I know exactly what's going on between you and (OM), and it needs to stop -- immediately. You've been lying to me, lying to our marriage counselor, and it's incredibly disrespectful to both of us, and to our family. You are an adult, and I cannot control you, but make no mistake -- I will not live in an open marriage. Because of what you've done, in order for me to feel safe in the marriage, I need 100% no contact and full transparency from you. If you're not willing to do that, I completely understand, but at that point I WILL be done and will take immediate steps to protect myself.
"Oh, and you have exactly five minutes to decide."
