Muslim man marrying a new Muslim

I recently converted to Islam and I am in a relationship with one muslim man. His family is making him married to one of his cousins and he dont have guts to take a stand. Now my family is hindu and they will make me marry a hindu man. I am afraid I will be in haram relation with him and the man whom I love is not willing to take a stand for me for his family. I am left in middle of nowhere. I can't live my life with a person who does shirk and is non believer plus my family don't know I have converted to Islam and they won't understand and force me to marry a hindu man. What should I do? Please help me. Please I can't leave Islam.
