How can you unknot the idea "I only want to have sex with my husband because he is the father of my children" without breaking marriage vows or having a divorce?

I think this statement is extremely misleading. It infers that women arent attracted to OM, it denies the reality of a 25% or greater cuckold rate, and is directly counter to biology's immutable directive to diversify the species, which is just as strong in women as it is in men. Its just practically spread out to be one every 4 years instead of 4 a year/month/week/ whatever.

As far as breaking marriage vows or divorce, those are just words and POP not worth the ink used to write them with. I have a stock certificate from ENRON. It has the same value as my marriage license. The value is based on perception and subject to fluctuation.. I think we know they are really secondary concerns once you have lost or calculatingly wrecked the emotional aspect of the R.
