LMAO! It is, isn't it?
Man, you don't need a pre-nup, you need to not marry this woman. If you insist on marrying her, then you need to INSIST on a pre-nup.
I had a friend this happened to - his wife was angry about his insistence, but it was a good thing he did it. They didn't last 5 years, and when they split, she tried to get half of his assets (including his house) despite the pre-nup. Didn't work.
