I think she's making excuses for her own decision to cut and run from her marriage.
I think if and when you guys reconcile -- or even if you don't, and someday she comes to grips with the truth of her decisions -- she will tell you that it was b.s., and that she was using this as an excuse.
I think she's re-writing your marital history to justify her waywardness.
I'm NOT excusing your behavior; I just think she's magnifying it, smelling your (justifiable) weakness on the issue, and using that as her excuse to flee the marriage.
