Alcoholism is like taking any other drug on a regular and it brings on paranoid episodes. It also bring so n depression.
As Yvette says he is only blackmailing you ,as he knows how to pull your strings and make you feel guilty about his wanting to kill himself.
You can block his email address so that you don;t have to read his mails, Also you canhave his number blocke don your phone. You do not need this kind of guilt thrown up on you, it is not your fault he drinks to that extrent. All he wants is someone to nurse him and cook and wash his dirty clothes. You must relaise that if he loved you deeply he would not blackmail you, I have seen this with many people over the years and have even experienced it myself with an ex husband who drank. It almost sent me round the bend ghavignto deal with him until one day bingo I igoned him totally in every way for I had had enough of his threats.......he later moved on, as they all do. He probably found another mug to put up with him !!!
Block all communication with him and if he tries to contact you you must go to police who will tell him to keep away from you, if he persists they will do something about it.
If you want nothing to do with this person DO NOT FEEL SORRY for him as that is what he wants for like I said he know how to pull your strings and make you feel guilty for his behaviour. Why should you feel guilty ? there is no reason , he is like he is and no one will ever change him. He will have to face reality and get on with his own life and if you keep on "helping and feeling sorry for him" he will never get any better. He is using you as a crutch to lean on. You must take away that crutch and let him go and get proper help. You do not need the stres of this in uyour liife as ;ife is stressfull enough for most people.
He is blaming you at this time for his behaviour by saying he cannot live with out you etc etc ............. remeber this...........you are no to blame for this........he is !!!!
Love and good luck to you,
