Yes I have walked away. Blocked his number. The only thing I did was let one of his friends know that he is not okay. I did this because he is a human being in need not because he was my boyfriend. I told his friend I cannot help him and he has no family so I felt someone who cares should know. This is a friend of his since they were 12, now 56. I only knew him a year so I had to walk away. I did all I could for him. I cannot save him nor anyone.
