notorious
I feel sorry for you reading your story. I think mojority of today’s men are not like your husband. I have never been this cruel to my wife like this. We still fight alot but I never cross my limits.
Your story is abviously very tragic but I very strongly disagree with one sentence in your story you wrote:
"I always had to be ready for his sexual needs, he could go on about that stupid hadith that according to him says that a wife who refuses (sex with) her husband will go to hell, that the angels will curse her and continue to curse her as long as her husband isn’t happy again 
, that can’t be Islam!) "
You should say Istaghfaar for saying ‘stupid hadith’. Whoevr quotes this Hadith, needs to understand the logic behind it and not take it to his advantage. Just because you don’t understand, you cant’t say “that can’t be Islam”.
May Allah forgive you .
