Gym company employee hustling a client.

A certain employee of gym company is trying to hustle me, she came to me in desperate need of urgent financial help. Well she needed money to buy electricity as her landlord installed meters without informing them and she was only getting paid the following week, at least that's the story she told me. Out of the goodness of my heart I loaned her the money in agreement that she will pay it back the following week when she gets paid, it's been 7 weeks and I still haven't received my money, instead she is now avoiding me and would be rude whenever I bump into her at gym. What does a guy in my position do in this case?
