When you fighting your fight you focus on the progress not on the outcome. You cannot predict that you'll ever win your WAS back, but you can fight for that possibility. These are baby steps.
If you don't pursue and become more mysterious and interesting they can see that as attractiveness and the fog will start clearing. Good memories return and they may start having second thoughts.
