Many possible specifics... the only reason that really matters in your situation is this...
not ready = doesn't want to date you
Later on... when or if this woman is 'ready' and you're single... you can give it a try. So I wouldn't worry about it anymore... see if there are some other women who are 'ready.'
And no... no positive connotations from this. It's a decline to date you.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
- James Allen
