I had a similar situation with my best friend who now I have a restraingin order on. WHo confronted my actual abuser in front of me...talk about secrets unleashed....as well as other things.....it is sometimes hard to accept that someone we love like family who we have shared so many great things with can change so suddenly without warning and we are left in the battlefield wondering how it happened. What makes it worse is when we fight it. Drugs tend to change a person's personality and morals. It sucks but we have to accept that the person we once were friends with is no longer the same person as we were friends with before.
