@vtrong123,
It's a daily struggle for me. I'm a dood, so by default I'm unqualified to judge what a woman means, but my best guess is something along the lines of, "Move along."
Or it could mean the opposite, like, "Try harder."
Or it could mean something completely different, like, "I've got my eyes on someone else right now, so I'm putting you on the back burner for a while to see if this other thing works out first. Don't go away, but don't try to come any closer, either, unless I give you a signal."
OK, I don't know. The more I think about it, the less confident of anything I say. Never mind.
