My girlfriend isn't very interested in having children, and she's very against being a stay-at-home mother. She doesn't want to take her husband's last name, nor share bank accounts. I feel like if we got married, she would get all the benefits without any of the risks. Since marriage is such a raw deal for men (no fault divorce, alimony, child support, etc.), I'm not sure I want to get married unless I'm getting everything I want out of marriage, which includes a wife to do the traditional household duties and raise my children while I'm working. I don't want to pay for my children to be at daycare when there is no reason my wife needs to be at work.

Am I being ridiculous? I have a really good life and I just feel like marrying someone could easily ruin it unless she's 100% devoted to me and our family.
