I would if C asked. I may just make one, anyway, because I am previously divorced and pragmatic enough to know that Reality can trump Love when it damn well feels like it.
I started out fully intending to always be married to my first husband, would never sign a prenup if he wanted one, love was more important, etc. Then our marriage went to shit and divorce was the best course of action. Fortunately, he was civil and didn't try to take my car or anything away (because I actually own more than he does), but a prenup would have saved my ass if he was going to be petty.
It's insurance is all, just like vehicle, life, home, etc insurance - for JUST IN CASE. Just because you make/sign one does not mean you fully intend to make it happen so it can be used. And it really helps protect what you have if your spouse should die and leave you holding the bag with their debts or even their funeral. A former coworker of mine had everything taken away from her - home, vehicles, horses, possessions - to pay off her late husband's debts. A prenup would have saved the stuff she bought in her name, instead of being grabbed by creditors simply because she was married to him.
