Divorce

Hello, I'm Nikhila and I'm 26 years old. I've been married for 5 years(got married in 2015). Got married in chennai. At present I'm in Banglore doing my LLB which i will complete in the year 2020 (june). even when i was living with him i had a lot of marital problems one being he was addicted to drugs (marijuana) and he was depressed and so he did not work properly. hence we both agreed to a time off where i suggested that i would study at banglore to which he agreed to. i told him that he would need to quit drugs and find work. Note: his father owns a small business and my husband just goes there under the guise of working and his father does not even pay him. Now, I have opportunity to further my law studies in the UK. While i told my husband this on 29.09.2019, he threatened to kill himself or create problems for me after he himself suggesting that i give him a divorce. he underwent rehabilitation this year for two moths and now is on psychiatric treatment. I'm at a loss on what to do since it feels like im stuck with no option at all.
