AFWAW... Well, I told you I know how to get them back, but I'm not so sure how to get rid of them.... Start chasing her again maybe... (just kidding....)
I would recommend doing it in increments. Start out by telling her that her idea of waiting a month until after your vacation is a good idea. Tell her that you want to take that month to think about things and that she can contact you after one month... (that may buy you at least a month)
Then after she contacts you after one month, you can do the same thing again and tell her you need more time or that you haven't changed your mind...
Just get her to leave you alone or back off for NOW.
Women are like bad pennies. You can't get rid of them.. (just kidding ladies)
