I am offering her an insight into her husband and how he feels. She is here because she mysteriously is in a quandry way her husband wants a cum receptacle rather than offer his forgiveness when she has apologized.
However, "I'm sorry" is just not enough and no matter how ernest she feels the apology is, she still is puzled why everything is not hunky dory now.
Well, men have lots of layers (not like chocolate cake or parfait, but like onions) and each one is in pain. When the affair is exposed, every lie, deception, askance look, etc is reinterpreted in the new light. And whole hosts of scenarios are played out in the husband's mind. He is now imagininghis wife eagerly meeting in a restraunt, touching hands, going to the den of inequity, kissing, carressing, removing dress, bra, panties, shoes, seduction, caresses, penetration, etc...
You get the picture.
Yet Lifline still chooses to engage her husband in the "You drove me to it and are to blame" when her temper gets in the way. Freudian subconscious is still justifying the affair to herself to repress it so she can feel comfortable with her sin and violation.
If not, she would be seeking true forgiveness when each and every misdeed brought forth the visceral pain, anxiety, and despair in greater measure in her than what her husband is feeling right now. When she can truly comiserate with her H, she will be taking the first true steps toward forgiveness and repair of the M.
But she has not. She still is at the "OK, I apologize already, lets get on with it" stage for her.
Sorry, but Lifeline has not penetrated down to the layer of her husband (remember the onion analogy) where he can know that she is feeling the true depth and breadth of his pain, betrayal, and is truly remorseful.
