C’mon man - maybe she decided to forgive and keep the marriage going for the sake of the family and because she loves the man. I’ve been married 15 years and to my knowledge we have been faithful. But I’ve also learned to love and be loved in a way that goes beyond a simplistic “you screw up and you’re out”. It probably sounded good for her to SAY that, but when confronted with the reality she went another way.
And that's what I'm calling out that social climber on.
This is a marriage of convenience...she made that abundantly clear.
