She isn't going to care if he knows. She thinks she is in love with the OM. Deeply in love. When he changes the accounts and stops paying on the phone bill etc..
She will call him in anger. She won't be thinking any such thoughts that he will expose. Remember. She thinks that the OM is leaving his wife, so exposing isn't going to enter her mind. She already thinks it IS exposed and that they are going to be happy ever after...(and it very well may be exposed. We want to KNOW for a FACT if it is. The only way to get that as a fact is to talk to the only person who can answer that. The OM's wife.) We need to know before we proceed to the next plan.
She will call and be angry and say.."why did you do that to our account. How dare you. I thought you wanted to work this out, but NOW I am done." (or something to that effect)
Just tell her.. "I have been doing some thinking and I decided that I thought this was the best thing for ME.
Then expect her to respond in more anger. Let her. Just say no more and stand by your original statement. Get those things done NOW. Exposing will be done as soon as we can find out how to contact the OM's wife. If you wait, you are running the chance of HER taking ALL of the money FIRST.
Don't worry. She isn't going to associate the money with exposure. She may thinnk you have an idea, but I would guarantee she will deny it if you asked her. Just let her believe that you are getting tough because you don't want to be with a woman who doesn't want to be with you.; Leave it at that.
