The nice guy, so desperate to give, chases all the women away. His giving, in fact, is a weakness and a selfishness — through it he seeks to validate himself. But the validation will not come to him who is weak in his heart. And the less the validation comes the more neurotic the need to give becomes. His giving seeks to manipulate the woman into giving him back the validation he seeks. But no woman will have this because he is not a man who can stand on his own. The nice guy, however, should not revert back to the bad boy type, so craved by the feminine; he must reach into his instinct and come to his strength through his weakness. He ought to become himself, create his boundaries, and become able to stand on his own.
A man who can only love or hate a woman, or a certain kind of woman, suffers an impotence of will. What leads him to her and what in her cripples him is a certain lack in his emotional and sexual life. His maturity is the maturity of his will, his ability to choose, and be aware of the moment where his choice is made, and his will to go one way or another activated.
