Money given to support someone

I met someone in 2016 april for marriage purpose. Guy was running a company and we got together. Later on he took lot of money from me to run his company. Now i know that he was genuine and there was a company and it was gaining good reputation in industry too. He used to send me mails and i also did my background check on this. Later on there were some legal issues with employess and many family issues because of which i again helped him with money. He kept saying he will return my money.His legal issues are still continuing and i know that they are true but still i want my money back and now all of a sudden he is saying he will return the money if his issues are resolved. I know he doesnt have money now but he will get and even if he doesnt get i still need it back. We have been fighting a lot lately cos of personal and financial issues. I am not going to take any action now but i wanna know what are my options if i decide to go to court. I am not in india and working overseas. where should i file the case if i want to go for this in future?
