My husbands grandma is dying

Sa

So my husband is in the navy, he’s in A school right now but i just got the news his grandma has stage 4 cancer she at most has a year left. When they told me his aunt and i were both very serious about the fact that we weren’t telling him until he was done with school. He’s coming home in 3 weeks so it isn’t that far out. I knew finding out this news in school would seriously hurt him plus a lot is going on with his mom right now as well. His aunt also wanted to wait to tell his mom because she’s going through a lot at the moment and it was just awful timing to tell either of them. Well today i got a call from my husband saying that he knew. His grandma called his mom and she called him to tell him the news. I understand it’s something he needs to know but i have never even seen him so messed up. He was telling me he doesn’t know if he can finish school, this has been months and months of him being away and it’s almost over now. I’m so mad that they told him. I wish they would of stuck to the plan. He set up a meeting to go talk to a chaplain Monday but i don’t even know what to say to him right now to help him. The scariest part is i was just with his grandma the other day and you would never know anything is wrong at all... this has been a week from hell.
