So you are planning for your marriage to fail? Sounds mighty non-Christian to me.
As my husband knows, I take the "til death do us part" portion of the vows
very seriously. If I ever want to "cash in" my husband, it will be with a hit man, not a lawyer or accountant.
If your wife knows that you are planning all these things, she already has grounds for divorce. I believe it is "spousal cruelty." Meaning that one partner treated the other in such a way that the marriage is broken and insupportable.
