Well, the fact that you don't believe in sex before marriage changes it entirely. You have your own moral values, but don't expect everyone else to agree. And I like how you didn't comment on my facts at all :) really show's that you dont care about facts, you just want to blame women for their behaviour. It takes two to tango - man and woman.
And regarding single mothers, how do a woman become one? It's most commonly because the man doesn't take responsibility for his actions and leave his child.
I don't understand 1 nightstands either. I like the idea of being with one person forever, but that's my own opinion, and I don't judge others by how they chose to live. It's their own choice.
