We're not married. We need to sign on pre-nup agreements even if

I'm not motivated to marry him--I don't want to face the legal discussion that will make both of us uncomfortable. But as we would have a kid together my kid should get what he/she deserves which is a comfort for me- even the lawyer thinks it's a fair solution unless our kid is the beneficiary on his will. I can understand that every man loves independant woman and thus I don't complain much about our differece, especially his family members treat each other similar way -- they settle some small payments as little as $20 between siblings(they all have similar wealth). It's just we don't have maximum synergy: wherever we travel to we go business/first class, stay in expensive hotel, he donates thousands every year, buy unnecessary stuff with big bucks... but he does not think necessary to support my kid's study or my personal expense(clothes, study, cosmetics etc.) while I don't have income. Maybe he does not want me to waste my talents & investment on my education and I don't blame him much--it's just a bit weird sometimes. And that's why I really wonder why some sisters here take it for granted that marry a rich man will be a warranty for her life -- how do you know you will have any shares of his wealth?
