But we all know that world is not just black and white. Marriages nowadays always start with good intentions, love and trust. Why would they marry in the first place, otherwise? Sometimes though things turn bitter. A lot. That's why divorce exists. Would you like then to spend all the rest of your life to share all your income with someone that maybe you end hating? Especially when after divorce you find someone who finally is the right one and you want to build a family? That's why pre-nups exist. They are not lack of trust in the first place. They are a way to be safe just in case something will happen, despite totally hoping for the contrary. It's looking at marriage pragmatically, since all the other decisions were probably already made on an emotional basis.
