Reading this thread and the breaking up thread… I think you’d be wise to have a prenup with any future potential bride. The prenup would take away your financial fears that your bride is out to get your assets.
You seem to assume all women are gold diggers and have enough anger about it that I would guess you’d be unsuccessful at marriage.
FWIW – my BFF had to pay her ex a lump sum alimony payment. It totally sucked for her because she lost her job in the dot.com bust right before it was due (18 months after the dissolution.) So alimony goes both ways.
