I think the most important thing is to be true to yourself.

I'm just a woman. And as a woman， I have no way to make money， not enough to earn a living and support my family. Even if I had my own money， which I don’t， it would belong to my husband the minute we were married. If we had children they would belong to him， not me. They would be his property. So don’t sit there and tell me that marriage isn’t an economic proposition， because it is.
