Is he still grieving what is going on?

i havent heard from my boyfriend in a week an im a little conerned. his friend died a week ago and everybodys been calling him but the phone just rang and rang he hasnt been picking up. his mother told me the unfournate news ab his friend dying since i couldnt get in touch with him. its tragic really, especially since his brother died last year. i really hope he hasnt done anythin tragic to himself because boys dont usually grieve this long.
