Mate, she is just blowing smoke up everybody's asses. That is such bullchit. I mean, you do realize it, don't you? IT IS NOT THE FCUCKIN' ISSUE, SHE IS MAKING $HIT UP.
If you were to proclaim that you'd forgive her, she would just move onto another silly excuse (like the dog farts, or you like prepacked salad, or something).
And she should be the one begging for a third chance...
