Can i divorse my husband in islam ? (please read details)?

ok so im a young muslim lady, and my mother got me married about 10months ago (my mum is white but converted to islam when she married my dad but shes not practising - mum & dad are divorsed because he got a 2nd wife), my dad didnt agree with the marriage and didnt want it to go ahead (but he was in another country so he couldnt stop it), but i dont view marriage as a joke, i always wanted you know to be married for life, so i tried to make the marriage work, but now after 10months i can see that the marriage isnt going to work. i try my best to be practising, i pray every day, read Quran everyday, fast not only ramadan but also try and fast eery monday and thursday, i wasnt brought up very practising, but i am trying so hard to learn more and more about islam and to be a good muslim. my husband though is not like this, i was living with him for 6months before he sent me back to live with my mum (as he was taking all my money untill it ran out so he sent me back to my mum in the uk to work - he lives in morocco). he drinks, smokes, does drugs occasionally. he tries to stop me from praying, and doesnt like me learning about islam. he doesnt work, the money i got for my dowry he took back, and also took over �8,500 from me. he refuses to work, refuses to support me financially (and i am having to give up work for health reasons). he has committed adultery on many occasions. he abuses me physically, but mainly emotionally. i know that i cant be with him because of how he is, but he refuses to change. i was just wondering islamically do i have the right to divorse him ( we have talked about the subject and he has refused to divorse me, he said the only way he will divorse me is he will go and kill himself then i will not longer be married). please if anyone can give advise, and islamically what should i do ? do i have to stay with him ? or am i able to get a divorse ? thank you to anyone who answers
