You had an outbreak, or she recently had an outbreak?
Just because she has it doesn't mean you'll get it. If you're male, and you were in a long term, monogamous relationship with her, there would only be a 4% chance that you'd get it from her over the course of a year.
If you get symptoms, you need to see a doctor. The best thing to take is antivirals, which are pretty inexpensive, even without insurance. You can go to an STD clinic or health department if you don't have health insurance, and they can check you out.
