What does "until next time mean" coming from a woman?

An older woman responded to my instant chat and it said, "Goodnight, until next time" at the end.

What exactly does it mean, does it mean that she is looking forward to chatting to me again, or does it mean that she isn't interested in my e-mails?

Bear in mind she has told me over the chat that I am 'fine looking and handsome.'
