An ex of mine, after 8 months of no contact, randomly messaged me on facebook telling me she had about us having sex. The conversation was brief and I asked a question, something like (Where is that located?) but she didn't respond until the next after I messaged her again. Facebook showed that she's been online several times throughout the day. I asked another question that didn't get answered until like 2 days later. So now I'm like is she wasting my time or what. I'm not wanting a relationship from her, but I don't interested in knowing how she's doing, and I hate not being responded to.
