Thanks for reading and asking this question. I generally try not to write from a woman trying to "tell men what to do" but here's my advice:
Men who are genuinely interested in a woman for the right reasons should 1. express their intentions with clarity 2. take initiative and 3. politely refuse to play games.
If a woman is incapable or chooses not to respond with clarity, or says no when he takes initiative, he has his answer and should move on.
There is nothing more attractive than a man who operates with confidence and does not tolerate disrespect. In the example I reference in this article, the best thing the man could do would be to remove himself from the situation and no longer communicate with that particular woman. Sticking around to be played with and disrespected will never lead to a happy or healthy relationship.
