What did he see in her? It certainly was not her looks! I think it was the fact that she was also in a broken relationship. I think she really played that card for all it was worth. I know they talked about it a lot. My H was not the first PA she has had. I'm sure she pursued him for all she was worth thinking she was winning herself quite a prize. Not that my H was innocent in it, but I really think she had a bigger part in it that he did. And now he is seeing her for what she really is ...
He has what I call a red-neck friend; a guy I don't care for. He hardly holds a job, parties all day, avoids responsibility... OW was living with this guy when she was living on the lamb, hiding out from the law to avoid a DUI charge. That's where H met her.
I really think he was just out of control and she walked into his life at the wrong time.
