Advice please

Ok so the last time I saw my BF was valentines day. My boyfriend is in the military and had drill the weekend after v-day, well he gets home and like 2 days later his brother finally came home from California (he's also in the military) After a few days go by I found out that his bestfriends brother passes away. Which really got him down, his bestfriend passed away a few years ago so losing his brother too was really unfortunate. Now, just to clarify that this is all in a week and a half time span. I'm just not sure how to help him. He hasnt spoken to me much and I know he is having a difficult time with everything which is fine. I know he needs to process everything in his own time. We dont live together and it's hard enough as it is to find time to get together. I just am not sure what I should do, if I should just give him space and let him figure things out or what. Any advice would be really appreciated. Thank you
