Actually the bottom line is this:
Life time alimony, life time commitment, and obligation to support child not biologically yours is a really really REALLY stupid shitty deals.
When people are forced to pay a life time alimony, people said, well, it’s their fault, they chose that deal.
My whole point is that some terms in marriage is so shitty there is no way it’s done consensually by significant number of people. Let’s face that. Who want to agree to pay child support for kids that’s not his? If you got a girl friend that want to live with you, and say look, I agree to have sex with you, but if I got knocked up by some other guy you have to pay. Would you sign that contract?
