SaucyJack - I do not belong to my father or my partner, likewise my name is my own. I wouldn't change my first name as this is what I have grown up with and identify with, it is who I am. I feel exactly the same about my surname.
I don’t think we should be advising women - anyone really - that they need to and should ‘marry for security’. Instead we should be encouraging women to want and to be financially independent, to be assertive in relationships, and for fathers to have a more direct responsibility towards their children – they're more than material worth. In the event of a separation, shouldn't joint custody be the norm? In any relationship, shouldn't childcare, housework, finances, leisure time all be split equally? Why is it that only women are expected to sacrifice their careers, earning potential, independence and free time when children are born?
If we keep promoting marriage as a way to make lower earners or potential SAHP secure, to the likely detriment (just look at divorce rates) of the other person, is it any wonder that some people (mainly men) are so unenthusiastic about marriage when they can, and often, have it all for nothing?
Interestingly, in Australia you can be considered a de-facto partner, whereby if you split from your partner, financial matters and any issues regarding children are determined in the same way as married couples.
