Anyone who has been assulted, raped, degraded and stigmatised will know why.
The question you should be asking is why depend on anyone at all? Our lives can function perfectly if we (both men and women) are growing as individuals.
This way we can all contribute to the growth and stability of society. Even matured and secured men don't like the pressure of being a woman's responsibility.
They need women they can collaborate with and not the liabilities. Only child-men, the insecure ones go for those women you described.
