Men need to understand that a woman who is suitable as someone to share his life with is rare. It is like searching through a pile of rubble hoping to find a gemstone.
When a man is rejected by a woman he has effortlessly eliminated a woman who is not suitable as someone with whom to share his life. Rejection is a favor done for you by an unsuitable woman. Thank her and move on. In rejecting you immediately she has saved you time and effort that would have been for naught.
It takes considerable time and effort to find the right woman to share your life. You must be patient.
