If you are really overwhelmed by a woman, then you shouldn't feel discouraged by an initial rejection. The verbal persistence sometimes really pays off. It might be the case that you were not convincing enough, that the woman is a shy person or that she just broke up with her man. There are many reasons for a first rejection. Be a charmer and start a new attempt. It is important to avoid being too pushy. Try to make clear that you just want to get to know her better.
