How about this one? I'm thinking I should do this tonight, but then I lose the element of surprise if I can't get a hold of OWH.
"I have decided that this isn't working for me. I will not live in an open marriage, and have you lie to me about it. I know all about your infidelity (changed from you and OW), and it's incredibly disrespectful. (added->) You are hurting me, the children and your family. I value myself and our family too much to keep doing this. I want to give this M my all and see if we can revive it, and that's impossible with a third party involved. I would like you to choose to end this affair and give our M the chance it deserves. I would like us both to be able to hold our heads high and say we were honest and did things the right way, regardless of what the outcome turns out to be."
You want to deliver this message to him right after you've had sex with him? I'm confused.
