Is 20 days a long time for no contact?

met this super hot girl 2 months ago, she just broke up. we go to the same spot once a week. we flirted a lot. she said I have such a sweet mouth. so I tried to move things forward and said we should go out some time. She replied "OK..." in text. So I called her up twice, no reply. I stopped contacting her. And I have not seen her for at that spot for 2 weeks in a row now and if I still don't see her this weekend it would be 20 days. Is 20 days a long time and strong indication that she is cutting me off?
