The POINT is that Ken you need to make it crystal clear to your wife that whatever deluded fantasy she's envisioning is NOT going to happen... It reads like you are trapping stuff she's typing so you are in the know here... Whatever she thinks is going to happen just detail out what she believes and tehn tell her it will absolutely NOT be the case... by LAW and CHOICE you will not accept it ...
Keep destroying those fantasies...
I would get a background check on OM...
This guy could be a child molester for all you know... If he's pushing this hard I would make a case for his potential as a sex offender to the police...
