Could ask her for her willingness to explore this and you would like the feedback by ___(end of week? end of month?___) if possible.
And if not able to give feedback by then, you would like to take it as a "no, not at this time."
No pressure, no harm, no foul.
Just.... info where you stand please. So you can take the info on board. Otherwise you have to move on without her -- and that could mean letting this go as a potential romance and keep it in the friend bucket.
