Decision workbook

On day two of the decision workbook, found in the decision class in the study vault, we are asked to make a model about a decision we listed on day 1. The instructions say to start with the action line. Is my decision the action line or the circumstance of this model?

C: married my husband 18 years ago
T: I am in a better relationship than I ever could have imagined
F: blessed
A: show up for him, show up for me, talk through everything, give us both grace, stay interested
R: my relationship is great and I keep looking for ways to keep it great

C:June 13th 18 years ago
A: married my husband 18 years ago

I am having a harder time coming up with a model where the decision is in the action line. But I want to uncover exactly what the exercise is meant to uncover.
