Life or no life

Few years ago I came across a girl and things went well. We fall into love and she moved with me to get some better career opportunities as well in the sillicon Welly. I promised to marry her but asked for a perfect time to bring it to my family's knowledge. Life was beautiful for a few months, then she started to rule my life. We had a great intimate time together. Later on she started to force me to talk to my parents. I did it and they denied. They stated the cultural differences. I told her that it's not working. She started threatening me the I will end my life if you don't do so. We moved apart to different cities. I tried to convince my parents many times but they are not ready to go with this. She is still on the same page, Marry me anyhow because we had physical relations. I'm scared of loosing everything. I already don't have any peace in life but now I don't see any life. You must have listened DO OR DIE but in my case it's DIE OR DIE
