Not really, no. I do think she was in a dark time, but I don't believe that 7 weeks later, and two weeks of ADs can change it that much. To me, telling your spouse you are not sure you want to be married is the marital equivalent of the a-bomb. You don't unleash it unless you are prepared for horrific effects. To think that she did it casually is not very likely.
