Sarah Michelle Gellar & Freddie Prinze Jr

I would say as many stay together as divorce. It's just nobody wants to here about a happily married couple. Also it seems a lot easier for celebrity to get divorced than a regular person. Not forgetting marriages for publicity.
Well the divorce rated has been going down since 90s. Divorce rates were actually and higher in 80s and 70s. Also the 50% divorce rate is actually a myth.
Why bother marriage? You don't have to get married it's not for everyone and that's perfectly fine.
