If the answer to either question is "no",then I can't see him having done anything so wrong as to entitle her to $40K.
Yah,cruising the web for babes is a good reason for her to dump him.And not having told her of his marriage also gives her good reason to be ticked off.
But not to the tune of $40K.
She shouldn't have been too shocked, seeing as that's how she met him.
