Actions like, taking the SIA course, getting the license, and getting work lined up? You mean the stuff that had already been going on for a few months?Nothing you could have said in 6h that you didn't say in 4 years wouldn't change a damn thing.

Instead of taking the hit, giving it a month to think of a plan and acting to prove that, you just left over the weekend. How is it supposed to change her mind?
