Is willing to commit to the right relationship. Is honest and trustworthy. Is willing to cooperate, compromise and communicate. Is able to express and receive affection. Supports rather than competes.
Men personifying the above characteristics exist, and in significant numbers.
Thus, in the real world, the world untouched and forever untouchable by something so ephemeral as a wish, nice men exist. But most women live in a different reality, and in that reality such men do not exist. So, nice guys are forever condemned to an evanescent existence, passing through the lives of women like whispers in the night. Most women assure nurturing men finish last. They snub them, and do it so casually and with such arrogance, as if they were God's gift to men and we should be grateful for being allowed to breathe the same air.
