Erectile Dysfunction

[desperate4help]

pls help if you can...i am the girlfriend of a wonderful man whom i love very much. trouble is we are being torn apart by ED. We have not had intercourse in at least 1 yr. He won't touch me, nor does he show any interest in being intimate with me. Most of the time when I have tried to initiate, he recoils from me--so as a result I have not done that too often, because I can't handle the rejection.
We used to take Cialis for us to have intercourse but he stopped...I don't know know why because he will not discuss the issue with me. AT ALL. Everytime I ask for us to try something, (pills, erotica, counseling, etc.) he clams up and gets absolutely furious, and mean. He will literally get up from the table and leave, or hang up on me if we are talking on the phone. He refuses to talk with me on this issue and it is tearing us apart. I feel so rejected, and I don't know what to do to help him I KNOW he feels alone and is depressed about it, but he will not open up to me.
I NEED love and some sort of intimacy in my life...how can I get him to understand that I also have needs that need to be met, and that I don't want to criticize. I want to help!
Why won't he let me 'in' to help US? It is making me so depressed I don't know what to do anymore.
We are drowning, and sometimes I just want to die...!!!
HELP!!
