I say that because step 11 kind of supercedes all the others. Lust can be a hard one to tame!! Almost got me married once, actually twice, but the first one was oh-so-close. I just woke up one morning (well, actually, a series of mornings but one day, I gave up on the battle) and realized that it wasn't going to work despite my best efforts. And it was all my effort - she had just been going along for the free ride.
That's the cause of much of the problem. You can go to any singles' bar and see the married men removing their wedding bands and also check what kind of women attract the most men. Men who choose poorly shouldn't complain so much about the consequences of their own choices, often the most they know about a woman they marry is her bra size.
Perhaps Moore's Law can be of help.
I hope that someday, someone invents a holodeck like the one in Star Trek, and then men can go inside and have all the risk-free sex that they want. When the real women find out that they are no longer of any use, then maybe they will consider treating men better.
