The idea that if you're a man*, and you get divorced, that the woman "takes half your shit" really, really, bothers me. Because what it's implying is, that if marital assets are split fifty-fifty... and she takes half the assets... and she's taking "half his shit"... well, it's implying that none of it was hers to start with. That everything is his, his, his. And that's pretty problematic. The easiest angle to address this from is that where both partners are working and making similar amounts of money. Is she really taking half your shit, when half of the money that bought that shit came from her? No. That should be obvious.
So, what about when she isn't working, when she's a housewife, or a stay at home mom? Guess what-- even if the income is solely yours, it still isn't all "your" shit. Because one of the fundamental parts of marriage is that the two of you are becoming a unit-- and if one partner doesn't work, they're still a full part of that unit. Things that are brought into the marriage belong to both partners, not just one of them-- because this is supposed to be a joining of lives, not just a convenient roommate situation. Everything belongs to one partner only in the sense that everything also belongs to the other partner. They're both co owners in everything. Because it's a partnership.
If your view on marriage is one where you're suspicious that your partner would "take half your shit", you might be a little too selfish for marriage-- and if your partner is the kind of person who might try to screw you over in a divorce, maybe you should think again about why you want to marry them. I guess part of this just goes back to my belief that marriage should be a partnership, a unity formed of two souls, in which you both really care for each other, and in which anything one of you has is freely shared with the other, in which both people act for the good of the partnership, and act with love, rather than with reality-tv style selfishness. I know that divorce has got to be absolutely awful, but it's no excuse for either partner to become overwhelming selfish and possessive-- even though I know that a lot of divorces come down to couples fighting over who gets the china that they both hated. But hurting people shouldn't be the norm, and it shouldn't be expected, and it especially shouldn't be encouraged. And when you're talking about her taking "half your shit" and it's a hypothetical, then you are encouraging that selfish behavior and you are encouraging it from both sides. And that is reprehensible.
*I'm assuming a straight couple for this, because while I see straight guys complaining about the possibility of a future partner someday "taking half his shit", I haven't seen it from gay men or women.
