As long as we are talking about friends, ironically two of my friends got divorced around five years ago just as I was getting married.
First couple were a little wild (smoked, drank, partied) and seemed like they were made for each other... problem was the gal was an overachiever and she took partying to the next level... then she started cheating... they tried to get together a few times but he couldn't get over the cheating and she didn't want to mellow out on the partying... he got a really good lawyer and cut her loose to the tune of around $10K

Second couple met in college and we best buddies and lovers... for about twenty years... then she became a crazy cat/dog lady and lost all interest in sex... my (best) buddy hung in there for another ten years but when he finally brought up the subject she was happy about the idea and they agreed how to split things up, ended up just paying for paperwork, around $2K.
