In the event of something happening, I'd still give half to her.
what, even if she cheated on you with another guy, you'd still give her half? Don't say this is impossible, you never know with women
That would be up to to the court to decide. Usually even cheating partners get half of the stuff. It's different with children. The ones that are blamed for the destruction of marriage usually don't get them, but they still get money because what you earn during the course of marriage belongs to both of you.
