sorry your going thru this
the thing is, he KNOWS your there for him thats why he keeps calling after hes been out using
as far as helping him goes the only way you can truely Help him is to NOT help him
drugs are every where its not just on his job
stick around read the sticky notes others will be along soon with support
also its a good idea to look for an alanon meeting or a naranon meeting to learn about how to care for yourself
