I have looked into this matter before, and had learned that the divorce rate did increase over a period of time from the early years of this century, but recently? I'm not sure. I also don't recall if it has gotten as high as around 50% yet, but it may not be too far below that. I do have some information about that on hand, I know, but I'd have to go look for it.
Also, I moved this here since this location would be the best for the subject matter, I'd think !!
