This girl is a scammer, please don't get cheat

I met this girl on the Internet and he invited me to join this website and download mt5 as an online financial management platform. I just started to invest a little money into it. He said that my money is too little and I invested another 10,000 US dollars. He said this can make more profit. Later, he invested 18,000 US dollars. Then he borrowed me 40,000 US dollars to my account until my account had 90,000 US dollars. Then he took me to start operations until I made a profit of 180,000 US dollars. Then my account was blocked. After the blockade, he said that he had to pay a security deposit of US$90,000 to unblock it. I really don’t know what to do. Where did I get so much money until now he can’t withdraw the money. He kept telling me to pay the security deposit. Keep asking me for money, I really don’t know what to do
