Don't leave her notes no... You say what you ahve to say and you exit.. do NOT LINGER in the meeting.. it should not last more than five or ten mins MAX
It is VERY important that you are CIVIL but FORCEFUL here... If you go begging and meandering around and blubbering and ASK her to end it instead of saying "I will NOT live in a home with you while you are openly cheating on me... And I will NOT cover up this infidleity.. It is disrespectful and cruel" and you walk away befroe it gets into a name calling match
If you are gentle or try to negotiate iwth her she will SMELL your FEAR and she will get forceful on you...
You HAVE to show her you are PISSED OFF and you will NOT ACCEPT a third party looming over your marriage's head at ALL...
If you go soft she will just give you a "I will decide what I am going to do and you can just go away for now" and then you are gonna fall apart...
You have to show her YOU are NOT going to accept the current arrangement she has going... You can't force her to stop seeing him, but you CAN show her you will not tolerate her rude behaviour by directing her to leave.
"This home was bought for an honest couple who work on their marraige... Not for cheaters... Find someplace else to stay "
And you walk away.. do NOT let her bait you into a fight
