Tell her to never trust that this once nice guy she married, will not turn nasty and vindictive.
When I got divorced, many, many moons ago (after a short 1yr. marriage), I left my apt. to go to work. When I returned at the end of the day, EVERYTHING was gone! Even my high school yearbooks, everything. Personal momentos from my childhood, my parents, etc. He charmed the landlord, explaining that he was moving his stuff out because of the divorce. And the weird thing is, my ex really was a nice guy. But he turned into a hateful bast**d once he realized the divorce was real. And I turned into a raving lunatic, trying to retrieve some of my personal things. The atty's were unsuccessful. I had to drop the whole thing and just get the divorce over with.
Moral of the story, divorces are rarely pleasant or reciprocal. It does reveal the disappointing side in a person.
Good luck to your friend. It will probably be the best thing she ever does.
