No - I would not think that God is “trying to tell you something” - other than it might be time to invest in a new rosary since your other one is kaputt. To think that there is a deeper message here is leaning a bit too much on the side of superstition. Our rosaries, crucifixes, icons, and other religious items have absolutely no magical properties. They are holy and deserve respect, but they are not God. They only remind us of Him. So the fact that it broke is simply because it physically was weakened and broke - Not divine intervention. Keep praying for hope if that is what you seek. Remember you can just pray for it alone without the “aid” of any other item.
