This is a very risky approach.

Taking no for no, and moving on with a smile to other women can show confidence, and maybe she will reconsider and take steps to get back into your social life.

In general, asking over and over again hoping for a different answer can signal desperation.

So it turns out in this situation, the spectrumy response of just taking a response at face value, can also be the best strategy for the "sexual marketplace".

That is in addition to it just being the right and decent thing to do, of course.
