It sounds like she suffers from stupid foolish pride. Foolish pride is so dumb. People can ruin their lives over foolish pride. She's rather carry on with some douche bag than just to admit how wrong she is. It's dumb. I know it. You know it, and yes, she knows it too. Still, regardless of whether we all know it, it doesn't mean she'll change course. Some people refuse to swallow their stupid foolish pride. Maybe google for some help coping with a spouse who is sticking to their stupid foolish pride. Maybe there are ways to chink some cracks in that armor. It might be worth a read.
