She was happily married for years. One night her hubby came home, after the kids were in bed, and they sat down to eat. For no explicable reason, he blindsided her by telling her he had had an affair at the beginning of their relationship with his ex wife.
For two days, she was a zombie emotionally. She finally had him move out. During the time he was gone, a long time male friend and business associate asked her to coffee. Sigh. Coffee became sex in a (imo) justifiable moment of weakness and confusion. She immediately told him it must never happen again, and she and her hubby eventually made up.
Her husband had a vasectomy almost two years ago....
She knows her cycles. She knows for a fact it is the other guy's.
Without being totally rude hateful person.. Put yourself in her shoes. What would you do??
Don't even waste my time with rudeness. It's already happened. Hurting her further does nothing but make you look bad.
