A romance scam. Invest crude oil

Around May 2020, I was added via Taiwan’s PAIRS dating software. Induced investment (and even helped me invest half of the amount), scammer: Wu Mingming (later LINE changed to Lin Yaxi), said he was from Hong Kong, After the deposit was about 3 to 4 times, the person disappeared! The first time I promised to transfer internationally, I was afraid of fraud, so I didn't send the money. Later, I withdrew 200 US dollars because of fear that I could not withdraw.
