Sorry to hear that, Kim...I lost my mom when I was 16, but it doesn't matter how old you are, it never really makes it any easier.
If that's what happens, you just gotta give him some time to grieve...if he's got any hobbies he likes to do with friends, maybe try to get them to take a few days and get away from things. Friends always make things better when men are feeling troubled. It's easier to look weak in front of the guys than the woman you love.
Will keep your family in my thoughts.
