My best friend of around 11 years and i arent getting along anymore, and im not sure why. He and i have always been very close and lately it just seems like hes pulling away from me..and when i try to find out whats wrong or even have simple conversation with him he gets very hostile like im doing something that hurts or bothers him. This really troubles me, and i have no idea what to do about it. I think he may have tried/is using crank now..idk if that could have anything to do with it. Anyone have any advice/or in a similar cituation?
