'She broke my heart and now wants me back'

I dated a girl for two weeks, after which she abruptly decided to end our relationship. I kept asking her why she had made that decision, but she said she just didn't feel comfortable being with me

I dated a girl for two weeks, after which she abruptly decided to end our relationship. I kept asking her why she had made that decision, but she said she just didn't feel comfortable being with me. I didn't ask her anything after that, even though I was extremely hurt by her decision, and we stopped seeing each other. A year passed and, a few days ago, she sent me a message on Facebook asking if I would like to meet her for coffee. I was taken aback, because she hadn't sent me a message until then, but I was curious, so I agreed. When we met, she told me she had ended our relationship because her best friend had told her that I had flirted with her. This isn't true, but that's what her friend said, because she was jealous of the fact that her friend had a boyfriend and she didn't. Apparently, her friend recently confessed to lying and this girl was upset and wanted to tell me about it. She asked if we could give the relationship another chance, but I have moved on and I am not even sure if she is lying about this. What should I do?
It really depends on how you feel about her, doesn't it? She broke your heart, and says she had a valid reason. If you believe her, and want her back in your life, she has given you the opportunity to make that happen. If you believe you are better off without her, nothing will have changed because you have survived a year since that short relationship ended. The choice really is yours to make, after you evaluate your options and figure out what she means and how your life will be affected by her presence or absence. As for her lying, you may be able to tell if she is being untruthful fairly quickly after spending time with her. Meet for coffee again if you can't make up your mind.
