Rape on false promise, what can be done

My case is that I was in a relationship with a Muslim guy for 4 years when I was 17 years old. He promised me and proposed me for marriage when I was 17 and I was not matured at that time so I blindly trusted him and we had physical relationship right from when I was not even 17 years old. At the very first time I even denied however he took me forcefully to his new flat claiming that he will show the new flat. This continued for 4 years. He also used to take money from me every time for petrol or some or the other reason and I also supported him financially. Later on by November 2016, I found him hiding and suspicious so I stopped helping him financially and the moment I stopped supporting, he said that he want to break up now and he was He also insulted my image and character between his friends who later on spread the same to other people which is affecting my social life
