confusion

ok....so i have been in a relationship with a guy for three years now ....but recently i decided to end it because i was not happy with the relationship and the way he was treating me. i told him that but he is not ready to accept it ...he is forcing this relationship nd  he wants to be with me by hook or crook.
        we dont even talk to each other these days. and i am really confused as i dont know what to do . we dont talk that much....he doesnt make me feel comfortable. now he is forcing me to stay with him and i dont want to.....what should i do now ? m confused
