Romance Scam, Fake Platform

I met a man named Zhang Zheng on IG in June. He began by deceiving me emotionally, saying that he was doing XAU real investment, and persuaded me to open an account and deposit money in a fake platform EXODUS, saying that he would help me to make investment. Then he persuaded me to participate in the platform newcomer activities, to deposit 1 million USDT. I said I have no money, but he said he would help me complete the activities. Initially, this scammer also deposited money, then he said that the funds were suppressed. The fake platform did not let me withdraw my money under different excuses, saying that the risk of my account was high, and asked me to deposit money again and pay the risk reserve margin. Until now, I still can't withdraw my money.
