1.  Post of pics of her, let's judge if she is worthy of starting a thread.
2.  Make sure that you nut up in her a  couple of times in her before she leaves.  Raw.. no condom, no pulling out.. send her off with a "going away package".
3.  Here is a good chance to hit her friends, use the sympathy of her leaving to your benefit.
4.  You can always visit her on vacation, it's no big deal.
Plus I suspect that paying for her company was costing you a fortune. Did you have to pay cash upfront or on a weekly basis?
