ruptured gallbladder

hello, my boyrfiend and I checked him into the hospital today for vomiting nausea and sharp pain in his abdoman. I am worried because he called work and the doctors said they think he may have a ruptured gallbladder. I am worried because I don't know if it is fatal, how much pain is he in, but I guess my real question is just how sick is he? How severe is this? Is he going to be okay? What kind of treatment will he have to go through? I am really confused and could use any help I can get.
