Amber,
He will feel much better with help from his friends, he needs to tell them. I have always been, and continue to be, a do it for my self kind of guy. Im not one of those warm and fuzzy kind of guys but it really helps to have someone to talk to that is close, but not too close. Please remember, as Gary points out, inoperable is not always bad news with this type of cancer and even that can change after he completes his other treatments.
