I don’t recall getting any really good advice, but I have some that I hand out.
When my then-girfriend and I were dating, I worked at a shop where love bloomed everywhere. There were four married couples in the department, itself, everyone else who was married was happily so, and mine was the fourth engagement in two years. I got engaged and was laid off. (Great timing!) The place I worked while we were engaged was the reverse: only two guys were happily married; there were seven divorces in process or just completed; all of the divorces were bitter ones (some having feuds running 8-10 years after the finalization). The complaints about alimony and legal fees were a normal theme of any non-work discussion.
I constantly heard was a stupid mistake I was making getting married.
Finally, at lunch one day I responded: You guys just did it wrong. When you get divorced, you pay your lawyer, you pay her, you pay her lawyer, and you pay the courts. If she dies, the insurance company pays you.
(Of course, having stated this publicly, I now have to go out of my way to make sure she never dies.)
