After Edward leaves Bella do they get back together again?

No Bella comes for him

coz Bella wants to do alot of dangerous things to hear edward in her head

and one day she was going cliff diving and Alice had a vision of her doing that and they think Bella comitted suicide and edward gos to the volturi (a group of ancient vampires) and asked them to kill him, because he is so sad about Bella's "death"

Alice goes back to forks and finds out that Bella is alive and they go to Italy to save edward and they get there in time.
