I want to divorce my husband And he doesn't want

I'm christian, first we got married in court and then in church on 2nd May 2018, my husband and their family members lied to me about his occupation, age and qualification, and after marriage I came to know about his financial condition and he was 41 and I was 30 when got married but he told that he was 37 , I'm not happy with him and I was thinking about divorce and I recently came to know that I'm 13 weeks pregnant but still I want to divorce him, sometimes he can't take my responsibilities and I told about divorce and he is saying that I will not sign the divorce papers and if you will leave me I will commit suicide. I don't know what to do please advice me. Waiting for your answer.
