Hasn't RSVP'd (now beyond a week overdue). FI talked to his parents, and they said that they weren't sure if FBIL was going to come, but probably not.
We knew this going in - he's a civilian who works for the Dept of Defense in FI's home state (many hours away) and has to be on-call most weekends.... but I still want to know for sure.
FI won't call his brother... or even email him (and I don't have that contact information). He says that since he didn't RSVP he's not coming - and since my future inlaws didn't think he'd be coming, that he's probably not. They're both adults. FI is 31. His brother is almost 42. I can't make either of them do anything that they don't want to do (even if it's just PICKING UP THE DAMNED PHONE).
This gives me a little case of the sads. So few people are coming just for FI (16 people of our 105 guest list), and I wish FBIL would come, too
FBIL's 14 y.o. daughter is coming though, so that's awesome (FBIL is long-divorced, future niece lives with her mom, but sees her dad every other weekend. She'll be coming up with FI's parents).
