Former friend reached out to me after 15 years, but seems uninterested in talking
A former friend whom I hadn't spoken to in nearly 15 years randomly sent me a friend request on Facebook and then messaged me. I accepted her request, but she's been keeping her messages very short. She asked what was new with me, and I wrote a paragraph, to which she just gave a one-word answer and that was it. Am I supposed to continue the conversation? I don't understand what the purpose was of her reaching out after all these years if she doesn't really seem interested in talking.
For some background info, I never "formally" ended our friendship. I just found out that back then she was spreading lies and saying nasty things about me behind my back, so I just kind of let myself fade out of her life.
