I know this is an old thread but how fucking sad that one could waste their life chasing after the dude that's rejected them time and time again all for this small hope that he'll have a change of heart and suddenly agree to marry the woman that's been stalking and harassing him for years.
Based on "Should have said yes", she may actually on some level prefer the chase with no plan or poise for if things were to actually go her way.
It may be closer to financially dominating her partner than the chase
