All I can do at this point is hope he is ok. Hate to be blunt, but there are really only two options as to why he hasn't reached back and I hope it's the positive of the two.
The reality is, from one day to the next, somebody is gonna stop posting on here and it could be any of us on any day. I for one can say that if you don't see me on here for over a month, I'm likely dead or in jail.
On a positive note, if Bullet came back, I guess there is still hope
