Ahhh ok. Thanks for replying. This makes sense to me. She's just living her life that you don't know much about, and your friendly message came up, she replied, and continued on with her life.

In order to get anywhere near relationship-status, there should be some pretty natural interactions between you and her that develop over time, where you're getting to know each other.

I think the ball is in her court. Let her initiate with you.
