Hmm
Having not been divorced, (my wife is my first - and only) ... I don't have the experience that you have ... so please just take my thoughts with a pinch of salt ....
and also ... many of the guys here who have been divorced before can give you a perspective ... but ....
I think that if you get a prenup, that you are kind of suggesting that the marriage will be weak and will possibly fail. I feel that it shows a lack of confidence in your nuptials.
That's my tuppence.
But if you didn't already, please read the bit above - not in bold
