I learned yesterday that Matt and Amy Roloff have filed for divorce after 27 years of marriage. They issued a press release about being proud of their accomplishments as a family and how they will continue to work side-by-side into the future, but that they aren't staying together.
There hasn't been too much public blame-gaming yet. The couple had separated a while ago. Matt said that there was a lot of tension between the two of them for a while. He admitted that they probably should have split up a while ago. Amy said that it wasn't her choice to separate, but admitted that they had a difficult time living together.
Incidentally, I discovered a new blog last night called "Keeping up with the Roloff family." I'll leave it up to you to figure out what they blog about. The comments on there can be pretty toxic -- particularly towards youngest son, 18-year-old Jacob Roloff. He seems to be pretty much over the show and the fandom. He's also fairly anti-religious at this point, which upsets the show's evangelical fans. But the blog itself is very good. You should check it out if you get the chance.
